Two-factor authentication¶
Two-factor authentication (2FA) is a secure login method that combines two types of user authentication. If you use this method and the main password to the account is stolen or guessed, the attacker will not be able to log into the account without seeing the additional access codes.
At Serv00.com we use user passwords and temporary passwords generated by a software one-time password generator (e.g. Google Authenticator). 2FA can be used to log in via SSH, SFTP and DevilWEB panel.
