Sign in with Apple

What is Sign in with Apple?

Day One offers the option to Sign in with Apple to sign into a Day One Sync account. This is a new feature provided by Apple that allows users to sign into accounts or services without needing to create a separate login.

Data is still synced to Day One Sync, but this feature simplifies the sign-in process for users while also offering enhanced security and privacy. Sign in with Apple requires iOS 13 or later.

Details about this feature, including how to manage your information with Sign in with Apple, can be found on Apple’s website here.

When you see a Sign in with Apple button on a participating app or website, it means you can set up an account and sign in with your Apple ID. Instead of using a social media account, or filling out forms and choosing another new password, just tap the Sign in with Apple button, review your information, and sign in quickly and securely with Face ID, Touch ID, or your device passcode.

Sign in with Apple is built from the ground up to respect your privacy and keep you in control of your personal information. At your first sign-in, Day One can ask only for your name and email address to set up an account for you. You can use Hide My Email—Apple’s private email relay service—to create and share a unique, random email address that forwards to your personal email. That way you can receive useful messages from us without sharing your personal email address. Only the registered app or site developer can communicate with you using this email, and you can turn it off at any time. When choosing this option, users will see a “private relay” email address in the app and on their account at https://dayone.me/settings. This address is unique to you and the developer and follows this format: <unique-alphanumeric-string>@privaterelay.appleid.com

Sign in with Apple won’t track or profile you as you use your favorite apps and websites, and Apple retains only the information that’s needed to make sure you can sign in and manage your account.

You can learn more about Using Apple ID with Day One in our F.A.Q.

Note: If you deactivate or delete your private relay email without updating your account email, we won’t have any way to contact you, so we recommend keeping the private relay email active, or adding another email address to your account.

Update from CloudKit (legacy account migration)

If you have an older Day One Plus account from before Day One Sync existed (sometimes called a “legacy” or “CloudKit-only” account), you may run into one of these issues when you try to use it on a new device or after switching to Sign in with Apple:

• Signing in with Apple ID on Mac (or any new device) creates a brand-new, empty account instead of opening your existing Plus account, so your entries don’t appear and your devices look out of sync.
• You see “Sign in with Apple” errors when trying to log in.
• Adding an email and password from inside the app on your existing device doesn’t seem to stick, because it’s being added to the new account, not the old Plus one.

This happens because the option to sign in with an Apple ID previously used an older system from Apple called CloudKit. To migrate your old account to the modern Sign in with Apple, log into the existing account and trigger the update:

• In the Day One app: Settings > tap the name at the top > tap Update on the Sign in with Apple line.
• Or on the web: go to https://dayone.me/settings and log in.

You will see an error the first time, but then try again — the second attempt typically completes the migration. Once migrated, the account works with Sign in with Apple normally and you can sign in on all your devices.

If the migration still doesn’t work after a couple of attempts, or if you can’t access the device where the legacy account is signed in, please contact our support team for help.

macOS

On macOS, if presented with the password screen(s), please use the passcode to unlock the Mac. This is not shared with Day One.
