Data breaches happen every day, which is one reason people keep getting hacked. There's never been a better time to lock down your online accounts using multi-factor authentication (MFA), and using an authenticator app like 2FAS is a good start. It's free, collects minimal amounts of user data, works across all of your devices, has a helpful browser extension, and, unlike some competitors, doesn't require you to create an account to use it. Simply put, 2FAS is the best authenticator app we've tested, so it earns our Editors' Choice award.

2FAS is available for Android and iOS devices. There's also a browser extension for Brave, Chrome, Edge, Firefox, Opera, and Safari. I tested the 2FAS app using a Samsung Galaxy A71 5G, an iPhone 12 mini, and Google's Chrome browser. Notably, 2FAS doesn't offer apps for watchOS or wearOS. Of the apps I've reviewed, only Authy offers a wearable device app for watchOS users.

Authentication requires simple token generation, so it's nice when the associated apps are simple, too. You don't need to hand over an email address, phone number, or other personal information to use the app, and 2FAS does not require you to create an account.
