How can we get Google to show us our password for gmail (which is also Google One) ?

I assist my friend with electronics & web.
He uses Samsung Galaxy phone, and Samsung tablet.
His phone and tablet both remember his password, so logging in to gmail is not a problem.
However he does not remember his password, and would like to view it, and write it down somewhere.
I tried Perplexity, but all the suggested locations NEVER show the password.
Does anyone know how to view the password, so he can write it down ?

So basically forgot my gmail password and when i try to sign in and go to the enter password and try another way and try to recower account it says this: You can’t recover your account at this time because Google doesn’t have enough info to be sure this account is yours.

If you want to create a new account to use Google’s services, be sure to add a recovery phone or email address and keep them up to date.

If your account is managed with Family Link, we‘ve sent an email to your parent to change your password. Please help
