Does ios mail support modern authentication

iOS Mail app supports Modern Authentication (also known as OAuth 2.0) for Exchange accounts, but with some limitations.

Here's what you need to know:

  1. Exchange accounts only: Modern Authentication is supported for Exchange accounts, not for other types of accounts like IMAP, POP, or iCloud Mail.
  2. OAuth 2.0: iOS Mail uses OAuth 2.0 to authenticate with Exchange servers. This means you'll need to configure your Exchange account to use OAuth 2.0 authentication.
  3. Limitations: While Modern Authentication is supported, there are some limitations:
    • You can't use Modern Authentication with Exchange accounts that use Basic Authentication (username and password).
    • You can't use Modern Authentication with Exchange accounts that use NTLM authentication.
    • Some Exchange servers might not support Modern Authentication, so you might need to check with your Exchange administrator to confirm support.
  4. Configuration: To enable Modern Authentication for your Exchange account in iOS Mail, follow these steps:
    • Go to Settings > [your name] > Mail > Accounts > [your Exchange account].
    • Tap on "Account" and then "Advanced".
    • Scroll down to the "Authentication" section and toggle on "Use OAuth 2.0".
    • If prompted, sign in with your Exchange account credentials to authorize the OAuth 2.0 flow.

Keep in mind that Modern Authentication might not work if your Exchange server is not configured to support it or if there are issues with the OAuth 2.0 flow. If you encounter any issues, you can try contacting your Exchange administrator or Apple Support for further assistance.
