Two-factor authentication, or 2FA as it's commonly abbreviated, adds an extra step to your basic e-mail log-in procedure. Without
With 2FA, you enter in your username and password , and then you're done. The password is your single factor of authentication.Polaris has developed true two-factor authentication across Webmail, SMTP, POP and IMAP. You login to your service by entering your e-mail address and password, with the 6 digit code provided at the first step of the login. Then, you will be prompted to enter a 6-digit code generated by an app installed on your smartphone, appended to it. For example, when accessing WebMail or using your email client, if your regular password is: johndoe and the current code is 123456, enter: johndoe123456 in the password field, in order to authenticate.
See how an administrator can enable 2fa for a specific user in our respective 2fa wiki page.
After you have been granted access, check the "How to get it working - User panel" section in the link above for the user side configuration.
