My phone used to have wechat. But I have un-installed it after months of not using it.
Now, I install wechat (on the same phone). After entering my phone number, 2FA code with sms (also tried with password) and doing the puzzle, it gives me a set of numbers and ask my friend to verify my account. I'm stuck here.
Where do I enter that unique ID numbers on my friend's phone to verify?

I have tried creating a new account and the verification method is still the same:- it gives me a unique ID number.

I'm surprised that all my previous 2FA like voice recognitions go useless when it forces another person to verify my login.

How do I proceed?
