2FA Authenticator (2FAS) – An Open-Source 2FA App
2FA Authenticator, also known as 2FAS, is an easy-to-use, open-source app that everybody can use. What makes this app stand out from the rest is that it’s completely free. You can use it to its full capacity without having to worry about paying a subscription.
Besides that, 2FAS keeps all your tokens safe inside the app. Not only that, but you can also create backups on iCloud, so you’re sure to have access to any platform, even if you lose your iPhone. Additionally, you can also use the app offline if you want.
One of the good and bad things about 2FAS is that it doesn’t store any of your passwords. That means you won’t have to worry about the app stealing your data, but it does mean you won’t have the option to autofill your passwords whenever you want.
Since this is an open-source app, pretty much anyone can make improvements to it, which means the community behind the app is what makes this such a solid option.
