Create a Yahoo app password

  1. Sign in to Yahoo Account Security from a browser Yahoo recognizes.
  2. Under External connections, find the app-password control, name the app AeroMailer, and generate the password.
  3. Copy the generated credential into AeroMailer, not into your notes or a shared message. If Yahoo cannot offer an app password for your account, use Yahoo webmail or a compatible client; do not substitute your regular password.

Enter Yahoo’s mail servers

  • IMAP: imap.mail.yahoo.com, 993, TLS/SSL, mailbox INBOX.
  • SMTP: smtp.mail.yahoo.com, 465, SSL/TLS (the preset), or port 587 with STARTTLS if needed.
  • Use your full Yahoo email address and the generated app password for authentication.

Connect and test

Under Workspace → Accounts → Add Account, choose Yahoo.com and choose whether to send, receive, or both. If using the same approved credential for both connections, you can reuse the protected SMTP password. Test and create the account, then verify one send and receive. Remove the specific app password in Yahoo Account Security when retiring this connection.

See Yahoo’s IMAP and SMTP settings and Yahoo’s app password guide.
