Using Apple ID with Day One Sync

How is Apple ID used with Day One Sync?

Apple ID can be used to sign into your Day One Sync account. For new users of Day One and its sync service, this will make the sync set up process very simple—no additional email addresses or passwords will be needed. It also makes it easy to sign in to your sync account on other devices.

Does Day One store my Apple ID username and password?

It does not. Day One utilizes Apple’s secure services to authenticate and link your Apple ID with Day One Sync and never sees or stores your Apple ID username or password.

Do I have to use an Apple ID with Day One Sync?

No. If you’d prefer to use a separate username and password for Day One Sync, you can do this in the regular Day One account creation process.

I already have a Day One account. How do I use an Apple ID instead?

Please follow these steps:

iOS:

Go to Day One > Settings > tap your Name to open the “Edit Account” page.
Tap Link on the Sign In With Apple field and follow any additional on-screen instructions.

Mac:

Go to Day One > Settings > Sync
Click Link under Sign In With Apple and follow any additional on-screen instructions.

After linking your Apple ID, you’ll be able to use either your Apple ID or your original Day One account credentials when signing in.

Can I remove my password and keep only Sign in with Apple?

No. Once a password has been added to a Day One account, it can be changed but not removed while keeping Sign in with Apple as the only login method. You can still just use Sign in with Apple to log in day-to-day — the password will remain on the account but won’t be needed for regular use. See Removing Password/Email Login for the full explanation, including the export-and-recreate option if you need the password fully removed.
