Connect Yahoo Mail

Connect a Yahoo Mail account to AI Emaily using the IMAP tab and a Yahoo app password.

Yahoo Mail does not have a one-click button in AI Emaily, so you connect it through the IMAP tab. You sign in with your Yahoo address and a Yahoo app password instead of your normal login password.

Before you start

You need your Yahoo email address and a Yahoo app password. An app password is a separate, single-purpose password that Yahoo generates for apps that connect over IMAP.

Yahoo requires an app password whenever two-step verification is on. Use the app password in AI Emaily, not the password you type when signing in to Yahoo Mail in a browser.

Paste an app password, not your login password

Enter a Yahoo app password, never your normal Yahoo login password. AI Emaily envelope-encrypts every credential at rest and decrypts it only inside an isolated sync worker. Your credential is never logged or sent to your browser.

Create a Yahoo app password

1
Open Yahoo Account Security
Sign in to Yahoo, then go to Account Info, then Account Security.
2
Generate an app password
Select Generate app password (or Manage app passwords). If you do not see this option, turn on two-step verification first, then return to this screen.
3
Name the app
Enter a name you will recognize, such as AI Emaily, so you can revoke it later if needed.
4
Copy the password
Yahoo shows a generated password. Copy it now. It is shown only once, so keep it handy for the next step.

Add it to AI Emaily (IMAP tab)

1
Open Add mailbox
In AI Emaily, open Add mailbox and select the IMAP tab.
2
Enter your email
Enter your full Yahoo address, for example you@yahoo.com.
3
Paste the app password
Paste the Yahoo app password you generated. Do not use your normal Yahoo login password.
4
Confirm server settings
Use IMAP host imap.mail.yahoo.com on port 993 (SSL) and SMTP host smtp.mail.yahoo.com on port 465 (SSL) or 587. See the Server settings table below.
5
Save
AI Emaily verifies the connection before saving. If the test fails, a hint indicates which setting is likely wrong.

Server settings

Setting	Value
IMAP host	imap.mail.yahoo.com
IMAP port	993 (SSL)
SMTP host	smtp.mail.yahoo.com
SMTP port	465 (SSL) or 587
Password type	Yahoo app password

Troubleshooting

Authentication failed: you likely entered your normal Yahoo login password. Generate a Yahoo app password and paste that instead.
No app password option: turn on two-step verification in Account Security, then return to Generate app password.
App password rejected: it may have been revoked or mistyped. Generate a fresh one and paste it without extra spaces.
Connection refused or timeout: confirm IMAP host imap.mail.yahoo.com on port 993 and SMTP host smtp.mail.yahoo.com on port 465 or 587, all over SSL/TLS.
Sending fails but receiving works: check the SMTP host and port. Try 587 if 465 does not connect on your network.
