Description: `Create a new user access token.
User access tokens can be used to publish, subscribe, or perform any other user-specific tasks.
Tokens have full access, and can perform any task a user can do. They are meant to be used to
avoid spreading the password to various places.
Examples:
ntfy token add phil # Create token for user phil which never expires
ntfy token add --expires=2d phil # Create token for user phil which expires in 2 days
ntfy token add -e "tuesday, 8pm" phil # Create token for user phil which expires next Tuesday
ntfy token add -l backups phil # Create token for user phil with label "backups"

This is a server-only command. It directly reads from the user.db as defined in the server config
file server.yml. The command only works if 'auth-file' is properly defined.

Description: `Manage access tokens for individual users.
User access tokens can be used to publish, subscribe, or perform any other user-specific tasks.
Tokens have full access, and can perform any task a user can do. They are meant to be used to
avoid spreading the password to various places.
This is a server-only command. It directly manages the user.db as defined in the server config
file server.yml. The command only works if 'auth-file' is properly defined.
Examples:
ntfy token list # Shows list of tokens for all users
ntfy token list phil # Shows list of tokens for user phil
ntfy token add phil # Create token for user phil which never expires
ntfy token add --expires=2d phil # Create token for user phil which expires in 2 days
ntfy token del phil tk_th2srHVlxr... # Delete token
