Google Authenticator vs Microsoft Authenticator: Which Should You Choose?

In a world where digital threats are constantly evolving, strong authentication practices are no longer optional - they're essential.

Two of the most popular apps for two-factor authentication (2FA) are Google Authenticator and Microsoft Authenticator. While both tools serve the same fundamental purpose - providing a second layer of security - they differ in functionality, user experience, and features.

Here's a detailed breakdown to help you choose the right one.

• Are free to download and use.
• Work offline once set up.
• Are available on iOS and Android devices.
• Support multiple accounts from various providers (not just Google or Microsoft services).
