How can I best end sharing with the Ps4?

Moin I have such a question I unfortunately gave my former colleague my account data (I know stupid action learned it) and his ps4 was stolen and my data was still in his ps4 and tried to log in to me and then when he went off I have already changed the password so far nothing has happened but I have a bit of a queasy feeling even though my account is set to primary. I could say that he would stop that, but a thief would never do that

I still have the following questions

Does changing password bring what if, for example, I set automatic login whether he is also logged in automatically or if he forgot password whether he can still access my account?

Does Passcode do anything? If I make a pin to log in and out?

Does the 2-step verification (if it is spelled correctly) bring what?

Although my account is set to primary, would it still make sense to set it to deactivated?

And last question we assume we have deactivated it anyway. Should I then immediately change the password again and then set it back to primary? I really don't know that much about it.

I'm already sorry for this question and long text, but it would be really great if someone would explain this to me in detail, but I still feel uneasy

I don't know, but usually such accounts have the feature to log out of all devices. Try this if you didn't already change your password.

Ok, thank you in advance, but should I still change the password again when I press deactivate for security reasons?

I have no idea what you mean by disabled. I have never had a ps4. I would leave the primary console as well as the two-factor verification and I would change the password of the ps4 and, to be on the safe side, the password of the email address.

I said, although my account is set to primary, whether it would still make sense to set it to deactivated?

But thank you anyway for your trouble is just the restlessness in me
