TOTP tools for 2FA
Setting up a TOTP-based authentication application for two-factor authentication (2FA) is more secure than receiving codes via email or SMS. These applications generate the codes directly on the user's device and do not rely on external networks to function.
By not sending the codes via SMS or email, risks such as message interception, unauthorized email access, or attacks like SIM swapping are reduced. Furthermore, the codes are generated locally and change every few seconds, making it difficult for them to be reused or intercepted.
For this reason, tools like Google Authenticator, Microsoft Authenticator, or Authy are a recommended option to enhance account security.
Another advantage they have is the ability to configure the same token on multiple devices. Therefore, if you work as a team, all members could configure it and have access without relying on emails/phones of one of the members.
