Well, frankly saying I don't know nobody who have use different passwords.

Once somebody it seems have try, and as I remember there was even some
problems.

In theory yes, I was going implement such feature.
If it works 100% safe I don't know.

Totally agree!

For now just use the same password for all.

Btw, may be this will work:
    may be you can try passw of db to a table,
    if no error then this is correct password.
    and you can use it.

    if no, then you can think that password is other.
