Connect Yahoo Mail to Pop3Fetch

Step 1 — Confirm 2-step verification is on

Yahoo only lets you generate app passwords when 2-step verification is enabled on your account. If you already have it on, skip to Step 2.

1. Sign in at login.yahoo.com
2. Go to Account Security
3. Find Two-step verification and turn it on
4. Yahoo will guide you through verifying a phone number

Step 2 — Generate an app password

1. Still on the Account Security page, find Generate app password (or Manage app passwords)
2. Click it and enter a name — Pop3Fetch works well
3. Yahoo will display a 16-character password. Copy it now — Yahoo won't show it again.

Step 3 — Add Yahoo to Pop3Fetch

1. Sign in to app.pop3fetch.com
2. Click Add an account
3. Fill in:
   • IMAP host: imap.mail.yahoo.com
   • IMAP port: 993
   • Username: your full Yahoo email (e.g. yourname@yahoo.com)
   • Password: paste the app password from Step 2
4. Click Save

Pop3Fetch verifies the connection and starts importing on the next sync cycle — within 5 minutes on Basic, 1 minute on Pro.

Common issues

"Authentication failed"

You're probably using your regular Yahoo login password instead of the app password. Go back to Account Security and generate one (Step 2).

"Two-step verification required"

Yahoo's UI hides the "Generate app password" option until 2-step verification is turned on. Do Step 1 first.

Username must be the full email address

Use the complete address (yourname@yahoo.com), not just the local part. Yahoo's other domains — @ymail.com, @rocketmail.com, @yahoo.co.uk, etc. — all work the same way.

I lost the app password

Yahoo only displays each app password once. If you lost it, just generate a new one — you can have multiple. Revoke the old one from the same page if it's not in use anywhere else.

Notes

• App passwords don't expire on their own. They stay valid until you revoke them.
• Each app password should be used by exactly one service. If you also use Yahoo with another mail client, generate a separate password for it.
• Yahoo Mail Plus and AOL Mail (which Yahoo now operates) use the same IMAP server and procedure.
• Revoking the Pop3Fetch app password at Yahoo will immediately stop Pop3Fetch from importing — useful as a fast "off switch" if you ever need one.
