Right. There is nothing preventing Samsung or Huawei or Google or anyone else from making a similar system for their phones if it works as intended.

Afaik, they do have similar systems. I had to bypass the Samsung lock on my FIL's old phone, thankfully it was a phone that was possible to bypass because he didn't know his samsung account password (and didn't know he had one) and wasn't getting the reset mails either.

Oh that’s good to know. Thanks.
