Provider info for Delta Chat

Needs preparation.

To use Delta Chat with your Fastmail email address you have to generate a specific password for it.

You can do that in the Fastmail web interface at “Settings / Account: Password & Security / Third-Party-Apps: Add”:

  1. Enter your Password to be able to make changes. Then click “New App Password”.
  2. Choose a new name for the password.
  3. At access, choose “Mail (IMAP/POP/SMTP)”.
  4. Click “Generate password”.
  5. Enter the 16-digit password shown there into the Delta Chat password field. Careful - leave out the spaces, it’s just 16 digits. Better copy-paste it.

Afterwards you can use Delta Chat as usual.
