How can I do Help Friend Log In on WeChat?

It seems you have already found where is friend log in steps located. However I am still going to tell it for those who doesn’t know it.

You need to run WeChat and then tap on Chats. You will see an Account tab at the bottom of the screen. Click on that and tap Help Friend Log In on the menu.

You will see if you have reached a request there. If there is a request, Wechat will ask you to be a referrer of an account. If you accept it, you can’t do this service 3 months. You will need to be eligible to do it. The person who needs to be confirmed has to be in same country with you or you need to be from China mainland. Your account should be active more than a year. You need to have a WeChat Pay account.
