Use iOS 17’s Check In Feature to Reduce Worry

Use iOS 17’s Check In Feature to Reduce Worry

We’ve all had a friend or family member say, “Text me when you get home,” because they want the peace of mind from knowing you arrived safely. But what if something goes wrong—or you forget—so they never receive that text? They’ll be worried and won’t know where you are, if you’re OK, and so on.

In iOS 17, Apple has introduced the Check In feature to provide peace of mind—or in the worst case, to help emergency services. It’s conceptually simple. Before you leave to go somewhere, you create a Check In with someone—call them a safety partner—in Messages. You specify where you’re going and whether you’re driving, taking transit, or walking. Then, when you arrive, the Check In automatically ends, alerting your safety partner that you arrived. If you’re delayed en route, Check In takes that into account and extends the expected arrival time appropriately. If you fail to arrive, Check In shares your location and route with your safety partner. Also, if you make an Emergency SOS call or your iPhone or Apple Watch calls emergency services automatically during the Check In, it notifies your safety partner.

Not all situations revolve around following a specific route to a location, so Check In also supports timers. Perhaps a college student is going for an hour-long trail run and wants a friend to check on her if she’s not back as expected. She can use Check In to set a timer for 1 hour, share it with her friend, and when the timer ends, either tap the End button if she’s back or add more time if the run is going fine but taking longer than expected.

Although Check In may seem targeted at friends and family, it could have business uses as well. For instance, a destination Check In might work well for keeping tabs on a colleague traveling to a make-or-break pitch presentation.

Before you start using Check In with someone—in either direction—explain Check In to them and discuss an appropriate response if you or they fail to end Check In successfully. Responses should probably start with a quick text, followed by a phone call. If initial efforts to reach out are met with silence, contacting other people—friends, family members, neighbors, etc.—may be appropriate. At some point, depending on various factors, it will be time to call law enforcement. Of course, if the other person triggers an Emergency SOS during the Check In, call law enforcement immediately. At least in the US,if the person isn’t in your area, don’t call 911. Instead, find the law enforcement website for where the person is and call that organization’s 10-digit number. And here’s hoping it never comes to that

Create a Check In

To get started with Check In, follow these steps:

1.    In Messages, open a conversation with the person you want to be your safety partner (Check In doesn’t currently work with group conversations).

2. Tap the ⊕ button to the left of the message field, tap More at the bottom, and tap Check In.

3. The first time you invoke Check In, Messages walks you through a series of explanatory screens, one of which is important—the privacy level of the data shared with your safety partner if you don’t arrive. Select Full—we can see almost no reason why you wouldn’t want that person to be able to share your exact location and route with emergency services if something has gone wrong. (If necessary, tweak this setting later in Settings > Messages > Data.)

4.    On subsequent uses of Check In, an unsent card appears in the Messages conversation, usually set for an hour in the future. The card isn’t sent automatically so you can customize it before sending it.

5.    Tap the Edit button to adjust the timer or destination.

6. To change the timer duration, use the time picker and tap Done. Skip to the last step in this list.

7.    To set a destination instead of a timer, tap “When I arrive” at the top of the screen.

8.    Tap the Change button, and in the map, either search for a location or find one manually by pinching and zooming—touch and hold the map to drop a destination pin. At the bottom of the screen, select Small, Medium, or Large to set the size of the area in which you’ll arrive.

9.    Tap Done to close the map and then select Driving, Transit, or Walking so Check In can estimate your arrival time based on your method of transportation.

10.    If you want additional buffer time, tap Add Time and give yourself 15, 30, or 60 minutes beyond when Check In thinks you’ll arrive. This shouldn’t usually be necessary.

11. Tap Done.

12.    Once you’re back to the Check In card in the Messages conversation, tap the Send button to start the Check In.

Note that safety partners can’t reject Check In cards.

End a Check In

Once you trigger a Check In, it can end in a few ways. First, you can cancel it before the timer completes or you arrive at your destination. Second, it can end successfully when you tap End when the timer finishes or when you arrive at your specified location. Third and finally, there’s the core purpose of the Check In, which is to alert your safety partner if you fail to respond to a timer or arrive where and when you said you would.

Cancel:To cancel a Check In, tap the Details button on the Check In card in Messages, tap Cancel Check In, and agree that you don’t want your safety partner notified. Timer and destination Check Ins look slightly different but act the same way. Your safety partner will only see that the Check In card in Messages says it has ended.

End successfully: For a timer Check In to end successfully, you must respond when the iPhone prompts you (below left). All your safety partner sees when that happens is a note in the Check In card that the timer ended (below right). You don’t need to interact with your iPhone for a destination Check In to end successfully—just arrive at the specified location. The safety partner’s Check In card updates to say that you arrived.

●     Check In fails to end (initiator): If you don’t arrive at your destination or fail to tap End when prompted, Check In gives you the option of adding time (below left) but after 15 minutes, tells you that it has alerted your safety partner (below center and right).

Check In fails to end (safety partner): More interesting is what your safety partner sees if you fail to complete a Check In. They’ll be alerted and can tap Details to see your location, when your devices were last unlocked, and more. They then have to figure out the best way to respond given your setup conversation.

It can take some practice to become fluid with Check In, so it’s worth testing it in everyday situations before using it when it might really matter. Once you use it a few times, you may notice Siri Suggestions offering to start it for you, making it even easier to initiate regularly. We hope you find that it provides some peace of mind and, in the worst-case scenario, helps someone in need of emergency services.

Faster Copying of Two-Factor Authentication Codes from Messages

Faster Copying of Two-Factor Authentication Codes from Messages

One welcome feature of Safari is its automatic detection and auto-filling of SMS-based two-factor authentication codes you receive in Messages. It allows you to complete your login quickly, without having to retrieve the code from Messages. But what if you use a different Web browser, like Google Chrome, Firefox, Brave, or Arc? Apple doesn’t allow other developers access to those codes in Messages, but Messages itself recognizes the verification code, marking it with an underline. Rather than transcribing the code manually like an animal, you can Control-click the underlined numbers and choose Copy Code. Then, switch to your Web browser and press Command-V to paste it. Not all websites accept pasted codes, but most will, even if they present a custom interface.

Want to Password-Protect a PDF? Follow These Best Practices

Want to Password-Protect a PDF? Follow These Best Practices

We periodically field questions about password-protecting a PDF to prevent the wrong people from reading it. Lawyers want to ensure that drafts of legal documents don’t fall into the wrong hands, financial advisers want to keep confidential financial information private, and authors want to prevent their writing from being shared broadly on the Internet. Others don’t worry so much about a document being read but want to ensure that it can’t be changed or printed.

PDF provides options for password-protecting documents for just these reasons, and you can add such protection to your PDFs in both Apple’s Preview and Adobe Acrobat. We’ll explain how to do that, but before we do, we want to share some best practices to increase the likelihood that your PDFs will remain protected as you wish.

Also, if you’re looking for a comprehensive solution to protecting lots of documents for a wide variety of situations, you’d be better off investigating document digital rights management systems along the lines of LockLizard and Vitrium.

Best Practices for Password-Protecting PDFs

There’s no such thing as perfect security, especially when you want to share information with others rather than just keeping it as your own secret. But you can increase the security of shared documents with these best practices.

●     Use strong passwords: All PDF passwords should be longer than 12 characters and include uppercase and lowercase letters, numbers, and punctuation, without using dictionary words or well-known number/letter substitutions. A plethora of online PDF unlocking tools can remove weak passwords, and passwords should be strong enough to withstand brute force and dictionary attacks from a determined attacker who could bring significant computing resources to bear.

●     Focus on Document Open passwords: PDFs can have two passwords: the Document Open password that users must enter to open the document and a Permissions password that restricts actions like editing, printing, and copying. Even if you mainly want to restrict actions, it’s worth setting a Document Open password because the Permissions password’s restrictions can be bypassed by third-party utilities or by screenshots and Live Text.

●     Share passwords out of band: When sharing a protected PDF with someone, send them the password via a different communications channel. So, if you email the PDF, give them the password via Messages or a voice call. That way, if an attacker gains access to the PDF, they won’t also have the password sitting next to it.

●     Educate recipients: When you share a user password with someone else, they can give it to anyone they want and, depending on how you set things up, remove the protection from the document. In short, your document security is only as strong as your recipients want it to be, so make sure to communicate your wishes to them.

●     Watermark documents: Along those lines, it may be worth adding a header/footer or watermark that identifies the document as Confidential or Draft to clarify why it shouldn’t be shared.

●     Avoid online tools: Numerous websites offer PDF utility functions, such as adding passwords, watermarking, merging and splitting, conversion, and more. There’s no harm in using them with documents you don’t care about, but if you’re concerned enough to password-protect a PDF, don’t upload it to a website with unknown security and document retention policies.

●     Clear metadata: Passwords protect PDF content, but not necessarily metadata that might include the author’s name, employer, and keywords.

●     Use Adobe Acrobat: Apple’s Preview is a decent PDF app and offers basic password-protection capabilities, but for more protection capabilities and options, use the full-featured Adobe Acrobat. Preview is OK for those who need to protect an occasional PDF, but Acrobat is a better choice if protecting PDFs is essential for your situation.

Password-Protect a PDF Using Preview

It’s easy to add password protection to a PDF with Preview. Apple recommends a slightly fussier approach that involves setting the permissions during an export, although we didn’t find that it made any difference. Apple is likely trying to get you to make a copy so you don’t password-protect your original, but it’s easier to duplicate the file in the Finder first with File > Duplicate. Here’s the simple method:

1. With a copy of a PDF open in Preview, choose File > Edit Permissions to display the permissions dialog.

2.  Select Require Password To Open Document, and enter the desired Document Open password twice.

3. Deselect desired checkboxes in the Permissions section to restrict those activities.

4. Enter the Owner (Permissions) password twice at the bottom of the dialog. It should be different from the Document Open password. Either will open the document, but only the Owner (Permissions) password will allow the document to be printed, copied, or edited as per those checkboxes.

5. Click Apply and save the document.

Password-Protect a PDF Using Adobe Acrobat

Adobe has extensive instructions on password-protecting PDFs using Acrobat in different scenarios, but the basics are still simple.

1. With a copy of a PDF open in Acrobat, choose File > Protect Using Password to open the password dialog.

2.     Select Viewing to add a Document Open password or Editing to add a Permissions password.

3. Enter the password, and retype it to confirm it.

4..    Click Apply and save the document.

For a simple Document Open password, you’re all done, but if you want to set specific printing, editing, and copying restrictions, follow these steps:

1. Choose Edit > Protection > Security Properties to open the Document Properties dialog with the Security tab selected.

2. Next to Security Method (which should be set to Password Security), click Change Settings to open the Password Security - Settings dialog.

3.    In the Permissions section, select the desired options to restrict printing, editing, and copying text in various ways.

4.    Click OK and, when prompted, confirm the passwords you’ve entered.

5.    Dismiss the Document Properties dialog and save the document.

Password-protecting a PDF can be helpful when you want to ensure a PDF containing sensitive information can’t be viewed or edited by the wrong people. Make sure to use strong passwords since weak passwords are so easily removed!
