If the mobile phone is on the activation page, please visit the cloud hosting, click "Forgot Password" and enter the account you may have registered.
If the prompt "account information does not exist", it means that the account has not been registered; On the other hand, if you can enter the next interface normally, it means that the account has been registered, and you can reset the password according to the prompt before logging in.
If you still can't find the account according to the above steps, you can try to use a third party (QQ, Weibo, WeChat) to quickly log in the account for further verification.

You can also reset the password through the mobile client:
Not logged into Huawei account: go to phone settings > Huawei account > forgot password.
