Is it possible to create authorization only by password (without login)?

Question

Passwords

Most of my clients regularly forget their login and password for authorization, damn it!)
Is there a way to log in only with a password that comes in the form of SMS to a number, without a login? Those. such a common personal account for all users (single). There is no confidential information, access is equivalent and the information for all clients inside is the same.
Can this be done in WordPress?

Answer 1

well, if we have a phone attached, then there are no problems - we just generate a temporary simple code, which should be unique only within its validity (it can be a phone + code combination). For example, the code is valid for 20 minutes. For these 20 minutes, we can guarantee that the token is unique. The token comes to the phone (SMS for example) and after that we can authorize the dude using this token. All.

Answer 2

You can't use this password because user Petya uses it?

Answer 3

Let the phone number be the login - what's the problem?
The user will still need to indicate the number in order to receive SMS - that's the solution
