Documentation:
List of authentication sources.
Each entry is the authentication type with optional properties.
Entries are tried in the order in which they appear.
See Info node `(auth)Help for users' for details.

If an entry names a file with the ".gpg" extension and you have
EPA/EPG set up, the file will be encrypted and decrypted
automatically. See Info node `(epa)Encrypting/decrypting gpg files'
for details.

It's best to customize this with `M-x customize-variable' because the choices
can get pretty complex.

You can customize this variable.
