Risky Choice for 2FA
Using an authenticator app for 2FA is seen as a top choice for securing access to sensitive accounts over other methods. However, when the app stops loading, and instead crashes on open, you can easily lose access to these accounts if you’re relying on the app for 2FA and you don’t have backup methods configured (or physically accessible to you in the moment). This app is quite terrible in terms of its support and user experience. It did work, at one point, and now it doesn’t which means that I can never rely on it again. I’ve been slowing shifting to the Microsoft Authenticator app which has a superior user experience and feature set, is substantially more reliable, and works. I would not use this app if I were you.
Essential App, But No Cloud Backup
This is one of the most essential apps on my phone. I don’t know why I trust Google with my 2FA codes (I don’t really) but this is a very useful and important app. It is pretty basic as far as apps go, but it works for the intended purpose.
They just added the ability to transfer 2FA codes when upgrading to a new phone. They released this feature less than a month after the second wave of new iPhones came out… so less than a month ago I did the transfer manually, turning 2FA off and back on for my new phone across a dozen services. Some were easy to transfer, others were the opposite. It took over an hour. Their timing with this feature is awful, but at least it’s here now I suppose.
Do not use this app!
If you are in a situation where you are forced to use this app, be sure to keep backup codes so that you can access whatever applications you need to access in the event you lose your connection with Google authenticator. Because of a recent Facebook debacle and not knowing that it was necessary to save recovery codes with Google authenticator, I am now unable to access a 10+ year old Facebook account that includes some business connections. Facebook‘s issues are on them however, since I have a long-standing Google account, I don’t understand how I am unable to recover the connection with my Facebook account to allow me to get back in again. Is google authenticator completely unaffiliated with Google? Very disappointing and in 2021, I can’t believe things are this difficult for the average every day user.
