Gmail supports IMAP. Note that Google also prefers a more secure authentication protocol called XOAuth 2.0 which is currently not supported by K-9.
To configure access to Gmail in K-9, just follow the steps below:
- Enable IMAP in your Gmail settings.
If you have 2FA enabled for your Google account, visit https://myaccount.google.com/security#signin.
Click on “App Passwords” and generate a new password.
This is the password you will use for IMAP, instead of your Gmail password. - Open K-9 and set up a new account.
- Enter your full Gmail address and password, then select Next.
- On the next screen, you can give the account a nickname and choose the name to display on your outgoing messages.
- Tap Done.
