Google Authenticator was one of the first apps you could install on a phone for two-factor authentication to secure accounts. It works on more than just Google accounts, but it also suffers from being managed by Google, which is often slow to update features.

Top 5 Alternatives to Google Authenticator
This application from Cisco offers a feature called Duo Push. If a site works with it, the app may prompt you to tap to authenticate a connection instead of having to enter a code. And to prevent people from accessing your account without approval, you can deny requests and even mark the denied attempt as fraud.
Microsoft Authenticator is essentially the same as Google Authenticator, but powered by Microsoft with a slightly nicer layout. It also lets you sign in to Microsoft accounts, such as OneDrive and Outlook, with just a touch.
This one works well even if you don’t use LastPass to manage your passwords. It offers push notification verification with several big names like Amazon, Dropbox, Facebook and more, and it supports SMS and QR codes.
It has a decent layout, and its great advantage is that it can store your codes in the cloud, encrypted by password or biometric. That way, if you lose your phone, you won’t lose your second factor. Authy makes it easy to install on multiple devices and can generate codes you can use offline.

This one does not generate codes; it is a real physical key. It used to be that you needed a USB port on the device you were connecting to, but nowadays it also supports NFC and Bluetooth.
Whichever method you use, even if you stick with Google Authenticator, it’s good to have those multi-factors in the right place — at least until that passwordless future finally arrives.
