Using 1Password for password management

Once you have 1Password installed, it will automatically prompt to save your username and password when you log into Fastmail. It will also remember if you selected the "Keep me logged in" option.

To manually create a 1Password entry for Fastmail, the website url to use is https://www.fastmail.com/login/.

To alter the "Keep me logged in" option, edit the entry in 1Password and select/deselect the (unnamed) checkbox in the web form details.

Using 1Password with two-step verification

If you're using two-step verification, you can use 1Password to provide the authentication code, rather than needing an additional app.

  1. Within Fastmail, add a new security device of type authenticator app.
  2. Within 1Password, edit the Fastmail account and opt to add a "One-Time Password".
  3. Position the 1Password scanning window over the Fastmail QR code and save.
  4. Copy the 6 digit code out of 1Password and paste it into the Fastmail authenticator settings.
  5. Name the authenticator device in Fastmail and save.

Now when you log in to Fastmail using 1Password, you can use 1Password to generate the authenticator code and paste it into the Fastmail website.
