Add or remove accounts in Reminders on iPhone
In the Reminders app , you can use multiple accounts—such as iCloud, enterprise managed iCloud, Microsoft Exchange, Google, and Yahoo—and keep all your to-do lists in one place. Your reminders stay up to date on all your devices that use the same accounts.
Note: All Reminders features described in this guide are available when you use updated reminders in iCloud. Some features aren’t available when using other accounts.
Keep your reminders up to date on all your devices with iCloud
Go to Settings > [your name] > iCloud > Show All, then turn on Reminders.
Your reminders stored in iCloud—and any changes you make to them—appear on your iPhone, iPad, Apple Watch, and Mac where you’re signed in with the same Apple ID.
Update your reminders stored in iCloud
If you’ve been using Reminders with iOS 12 or earlier, you may need to update your reminders stored in iCloud to use features such as attachments, flags, list colors and icons, and more.
Go to Settings
> [your name] > iCloud > Show All, then make sure Reminders is turned on.
Open the Reminders app.
On the Welcome to Reminders screen, choose one of the following options:
Update Now: Begin the update process.
Update Later: A blue Update button appears above your lists; tap it when you’re ready to update your reminders.
Note: Updated reminders aren’t backward compatible with the Reminders app in earlier versions of iOS and macOS. See the Apple Support article Upgrading the Reminders app in iOS 13 or later.
Add other accounts
You can use the Reminders app to manage your to-do lists in other accounts, such as Microsoft Exchange, Google, and Yahoo.
Go to Settings
> Reminders > Accounts > Add Account.
Do one of the following:
Choose an account provider, then enter your account information.
If your account provider isn’t listed, tap Other, tap Add CalDAV Account, enter your account information, then turn on Reminders for that account.
Remove an account
When you remove an account, the reminders in that account no longer appear on your iPhone. The reminders remain in your internet account (for example, iCloud.com or Google) and any other devices you had already set up.
Temporarily stop using an account: Go to Settings
> Reminders > Accounts, tap the account, then turn off Reminders.
To view the reminders in that account on your iPhone again, turn on Reminders.
Delete an account: Go to Settings
> Reminders > Accounts, tap the account, then tap Sign Out (for an iCloud account) or Delete Account (for other accounts).
If you don’t see Sign Out or Delete Account, your account may be managed by your organization. See an administrator for removal instructions.
