Passwords are a necessary evil to keep all of your different accounts protected. However, passwords can easily be broken, especially if your employees are using simple passwords for the sake of convenience. Add an extra layer of protection by having your staff opt-in for two-factor authentication (2FA) for all their logins.
As the name suggests, two-factor authentication uses a two-step verification process to make sure the employee is who they say they are. For example, say someone wants to log in to their bank account. With 2FA, that person would need to enter their username and password, if done successfully, they would then have to follow a second step. In most cases, the second step would be entering a unique identifier that was sent to something only that person has access to (e.g. smartphone or email account).
