With Access Key, you need just tap on your phone to log in to Yahoo! Mail—with no password to type or forget.

The Passwords of Mice and Men…

Passwords are a lot like the plans we tend to make: either so simple that anyone can guess them or so difficult that we cannot remember and reproduce them even after we have written them down. Then, social engineering may trick you into handing out your password—or a keylogging application may record it for somebody else to use.

If passwords are dangerous, what can you do to secure your Yahoo!Mail account? Go without a password altogether?

Yes. Precisely.

Security Beyond Passwords for Yahoo! Mail

Yahoo! Mail lets you secure your account without a password—and much convenience.

Once you have set up Access Key for your account using the Yahoo! Mail apps for iOS or Android, the app is all you need to log in anywhere (with the exception of email programs that connect to Yahoo! Mail using IMAP or POP; for these, you will need to create passwords).

Logging in using Access Key is supremely convenient, too: when you open Yahoo! Mail, say, in a browser, an authentication request is sent to the app, and all you need to do is tap "Yes" to authorize it. (If you do not recognize a log-in request, you can also tap "No", of course, to deny access.)

What If You Lose Your Yahoo! Mail Access Key Phone?

Without a password to lose, what is there to lose?

Ah… your phone; but no worries! It’s not like it now is the key to your Yahoo! Mail account.

The key, of course, is not to lose the device you have set up for Yahoo! Mail Access Key.

Realistically, though, phones get lost and devices, too. So, to keep your Yahoo! Mail account secure:

  • Make sure your phone is securely locked; nobody can log in to your account if the phone without unlocking the device.
  • Make sure you have recovery phone numbers and email addresses specified for your Yahoo! Mail account so you can log in to your account and disable Access Key on the lost device. (See below.)
