My mail app says my Yahoo password is wrong, but it works on the website
Create a Yahoo app password in Account Security and type that into the app instead of your normal password.
Yahoo Email: Settings, Sign-In & Fixes
Yahoo Mail works in other mail apps, but most of them need a special Yahoo app password rather than the one you use on the website. Automatic forwarding is now a paid Yahoo feature.
Covers @yahoo.com, @ymail.com, @rocketmail.com. Run by Yahoo. Checked against Yahoo's own help pages, November 2026.
Yahoo email server settings
| Server | Address | Port | Security |
|---|---|---|---|
| Incoming (IMAP) | imap.mail.yahoo.com | 993 | SSL/TLS |
| Incoming (POP) | pop.mail.yahoo.com | 995 | SSL/TLS |
| Outgoing (SMTP) | smtp.mail.yahoo.com | 465 | SSL/TLS |
- Username: Your full email address (name@yahoo.com, @ymail.com or @rocketmail.com)
- Password: Apps without a built-in Yahoo sign-in need a Yahoo app password. Create one in Yahoo Account Security under "Generate app password" and use it instead of your normal password.
- Use IMAP if you read mail on more than one device; POP downloads mail to one device only.

Common Yahoo email problems
The automatic forwarding option is missing or asks me to upgrade
Yahoo has made automatic forwarding a paid feature. To read Yahoo mail elsewhere for free, add the account to the other app using IMAP.
I can't send from my computer's mail program
Turn on outgoing authentication and use smtp.mail.yahoo.com, port 465 with SSL (or 587), with the same login as incoming.
My POP app deleted mail or only shows the Inbox
Switch to IMAP (imap.mail.yahoo.com, port 993) so all your folders stay in sync.
Problems that look the same on every provider
Can't sign in, or the password stopped working
- Sign in on the provider's own webmail page first. If that works, the problem is your mail app, not the account.
- If webmail rejects the password, use the provider's "Forgot password" page. Never use a reset link from an email you did not ask for.
- Many providers now need a separate app password (or their own sign-in screen) for Outlook, Apple Mail and phone apps. Your normal password will not work there.
Not receiving emails
- Check Spam, Junk and any filters or "blocked senders" in webmail.
- Check whether the mailbox is full; most providers stop accepting mail at the storage limit.
- If your app shows nothing new but webmail does, remove and re-add the account in the app using IMAP.
Can't send, or emails are stuck in the Outbox
- Check the outgoing (SMTP) server, port and security on this page against your app; old guides often list ports that no longer work.
- Turn on "My outgoing server requires authentication" and use the same username and password as incoming.
- Large attachments are a common cause. Remove the attachment and try again.
Contacts are getting spam from my address
- Change the password from webmail, then sign out of all other sessions if the provider offers it.
- Check forwarding rules, filters and the reply-to address in settings; attackers often add a hidden forward.
- Turn on two-step verification, and update the password anywhere else you used the same one.
Setting it up on a new phone or computer
- Use IMAP rather than POP so mail stays in sync across your phone, computer and webmail.
- Enter your full email address as the username unless the provider says otherwise.
- If the app offers the provider by name (Yahoo, Google, Outlook), choose that instead of "Other".
