app password.
Any mail app that doesn't open Yahoo's own branded sign-in page needs an app password — your normal Yahoo password will be refused over IMAP, POP and SMTP.
Applies to yahoo.com, ymail.com, rocketmail.com addresses.
Step by step
How to create your app password.
- Sign in to your Yahoo Account Security page at login.yahoo.com/account/security.
- Under External connections, click Create app password.
- Enter a name for the app.
- Click Generate password.
- Use the password in your mail app, then click Done.
Worth knowing
- Unlike Google and Apple, Yahoo app passwords survive a password change — changing your Yahoo password does not invalidate them. The only way to revoke one is to delete it from the same screen.
- Yahoo gates who can create one: use a browser you've signed in to Yahoo from for several days, and avoid private/incognito windows. If it still fails, Yahoo's guidance is to use webmail or its own app.
- The same Account Security page covers Yahoo-run mailboxes on other brands, including Rogers, Frontier, AT&T and Cox addresses.
Or skip the app password entirely
BlueMail signs in to Yahoo Mail through the provider's own login screen, the same way your browser does — so there's no code to generate, copy or replace later, and nothing breaks the next time you change your password. Free on iOS, Android, macOS, Windows and Linux.
