Forgot password

Most days I use my iPad, and am never logged out. I’d like to login on my laptop but I do not remember my password. I clicked on ‘forgot my password’ and was emailed a link. The link takes me to a page to change my password however, it wants my current password in order to change the password. Confused as I don’t remember my password lol. If you could kindly help me, it would be greatly appreciated! Thanks.
