Do not store passwords as a plain text! Using [*] stars is not an option.

I'd strongly recommend to read this: Password Storage: How to do it.[^]

You can't.
Databases don't "know" that a column is sensitive information - they just store the data you give them. To "hide" a column with stars would mean the column text would have to be all stars, and that's not useful.

The solution is simple: Never store passwords in clear text - it is a major security risk. There is some information on how to do it here: Password Storage: How to do it.[^]

And remember: if you have any European Union users then GDPR applies and that means you need to handle passwords as sensitive data and store them in a safe and secure manner. Text is neither of those and the fines can be .... um ... outstanding. In December 2018 a German company received a relatively low fine of €20,000 for just that.
