How can I reset my password on paladins?

I want to sign up on my pc at paladins since I already have it on my nintendo switch. However, I do not know my password anymore and I do not know how to reset it…

Can someone help me there?

Use this link (https://my.hirezstudios.com/), go to "Can't Login", then "Forgot your Password?" and enter your username + email.

Then you can choose your new password, maybe you'll get an e-mail.

Do I have to confirm his e-mail? If so, I did not receive an e-mail to confirm mine

For this to work you have to have your e-mail verified, yes.
