  1. Log in to your account at
  2. From the menu in the top left, open the Settings → Password & Security screen.
  3. Type your existing password in the text box at the top and click the green "Unlock" button.
  4. Type your new password in the "New Password" text box, then type it again in the text box next to it to make sure we've got it right. Make sure you don't use the same password anywhere else (see below for why).
  5. Click the "Change Password" button.

Why it's important to not use the same password elsewhere

Your email is the key to your online world; you can reset your password at most other sites you use if you have access to your email. When you reuse your FastMail password at other sites, you're making it much easier for attackers to potentially break in to your account. Other sites often don't have the same high security measures as FastMail (such as compulsory HTTPS, locked-down servers, etc.), which makes them much easier for criminals to break in to. If they hold your email address and the same password that you use for FastMail, the attacker can then access your email account and get into everything else you use online.

What characters are allowed in passwords

FastMail provides a lot of different services over many different protocols. To ensure that your password is compatible with all of them, and the many (often slightly buggy) clients out there, we only allow the characters A-Z, a-z, 0-9 and !?@#$%^&*()-=_+[]{}.,:;<>/\|~"'`.

Setting a backup email address

In case you ever forget your password, it's useful to set a backup email address. This is where account recovery information is sent if you forget your username or password.
