Hi, everyone! This would be a great enhancement and a feature many people have been waiting for a long time to be integrated into original Google Play Services. I hope it will be integrated to microg soon too – it would be great. This is a key-feature to get the secure two-factor authentication without different passwords for every service running and I hope many services will upgrade there offers for this feature soon.

So I fully agree with @ale5000-git – We need it also :-)

As @mar-v-in mentioned in
#849 (comment)
this feature have not been integrated earlier because it have not been part of original Play services – this is now different! And he also mentioned it „shouldn't be too hard“ – so I am confident :-)
