Worried the webdesigner team will hold my domains hostage, they have passwords, usern

Hi,
the webdesigner has my password, and username, and I have 2 domains.
Now, when I look on WHois, it says registrar, Towson domains or something.
but, my host is afrihost.
Is it still in my name, I have 2 domains registered and am worried that the designer and team will take them hostage, and pass them on or something,
How do I know, they still belong to me, and how do I protect them or/and get them back.

“registrar” is the company that the domain name was registered through.

You are more interested in registrant; do you details show up anywhere on the whois report?

You have to trust people if you can not do things yourself. Why do you think they will cheat you?
