Multifactor authentication (MFA) is one of the most effective ways to enhance security, and with the rise of apps, such as Google Authenticator, the authentication method has become easier to deploy.

However, whether due to privacy concerns, a lack of updates (especially when it comes to open-source options), or preference, many choose to avoid Google Authenticator.

Fortunately, there’s no shortage of competitors on the market, each with distinct advantages. Here are some of the top Google Authenticator alternatives.
