This feature is one of the last ones, that MicroG is missing in order to fully replace GMS for daily use for me.

More disturbing is the fact that you need to enable "Register device" to have your "Receive push notifications" enabled, but when you register the device, Google thinks that it must authenticate you by the Google Prompt and you only have two options to authenticate:

1. Use another device to receive that Prompt
2. Use TOTP codes to authenticate

Both of these options are rather disturbing.

This needs to happen, I would be happy to help out with working on this if I knew where to start researching

Is there any update on this? It has become a pain lately since I cannot change the sensitive data on my google account without using this verification method because they give me no alternative, and I have no devices with google play services on it so I have been locked out of that part of my own account because of it.

Hopefully solve this problem in version 0.3.7.

I got the prompt when i installed microG as user app or through kernelSU but yesterday i tried to flash minmocroG in recovery and i got this problem too. I noticed that applications can register directly to GCM without prompt.

Ended up going back to play services because of this, help

The last time I saved some "backup codes" to access Google was a long time ago, and when I try them, Google refuses them all. I'm really scared about losing access to my account now that Google is pushing Google Prompt so hard (no text message option, it's greyed out). Now "Provider for Google Calendar" in Thunderbird is asking to re-authorize my Google account access, and I can't do it!

Is there any safe way forward? What's this "hopefully solved in 0.3.7" business? Is the prompt going to work soon?

Is there any other workaround so I don't lose my Google account just in case?

Google won't let me update authenticator codes without first doing the Google Prompt validation itself.

Now that I think about it, what would happen if I lost my phone? Surely whatever that process is needs to work to not lose my Google account. Is it safe enough to sign out of my Google account in MicroG? Will that lead to being able to use back-up authentication methods?

Any updates on this? It really is a problem as I happen to be dealing with logging in and out of my Google account quite often and I'm afraid my current workaround might stop working soon.

Edit: It already has stopped working. I was using the recovery option to get an SMS code.

It's been almost a year, is there any update to this? I have had to entirely stop using my google account for anything because I can't get into certain parts of it.

Before the two-step verification is resolved.
If you frequently log in or log out of your account.
You can turn on the profile - Select (Security) to enable the alternate verification code function. Save the backup verification code to your phone. When logging in, you can enter the backup verification code to log in to your Google account. There are ten verification codes in each group, and one backup verification code will be invalid once logged in. So remember to update regularly. This problem can be solved. This is the best solution at present. There is no other way.

In my experience, Google doesn't allow the alternative options like authenticator code or backup codes as long as it recognizes that I'm logged in on the phone in MicroG. Is it safe for me to log out of my Google account in MicroG as a way to make Google accept the alternative options?

Yes, alternative methods work just fine in my experience

My fear is that Google will make it harder for me to get into my account on my phone if I sign out… because I'm now feeling more paranoid about Google in general (and I really need to more figure out how to escape fully).
