Always so time consuming to have to deactivate and reactivate whenever you switched devices. ### 5/5 — So Awesome *2022-12-12, version 1.5.5* Why? Because I’ve been using this app for a long time now and it’s been reliable. ### 5/5 — Never have to remember passwords on all my devices *2022-12-11, version 1.5.5* I use Authenticator with edge browser on all my devices (Mac and PC). I never have to remember a password or account name. All the login info syncs across devices and I can use autocomplete synced with Authenticator to avoid typing passwords too. ### 5/5 — Great app *2022-12-08, version 1.5.5* Definitely a lot easier than remembering all the different at passwords ### 5/5 — 2Factor Authentication *2022-12-07, version 1.5.5* This is what we need. It adds a layer of protection. It's a constant battle these technologies get hacked that's why updates is so important. Even then we are vulnerable. The Internet was not designed for security. That is a weakness of it. God bless. Let us all keep freedom. Because we have freedom we take more risk. If we reduced risk we reduce freedom ### 5/5 — Needs easier account add, but over all great!! *2022-12-06, version 1.5.5* Love the security and verification process is a breeze. Adding accounts needs another secure and easy entry. Thank You ? ### 3/5 — New to this kind of setup, but Seems to be working… *2022-11-28, version 1.5.4* A little hazy on how this works, but seems to working as advertised so far. Right now I’m just following the a-b-c-1-2-3 instructions I received from my organization’s tech support. Hopefully that will get me where I need to eventually end up ## Frequently asked questions about Authenticator App ### What does this authenticator app do?
