This thread is frustrating. Everyone seems more interested in nitpicking the specifics of what OP is saying and are ignoring that a forum sends you your password (not an automatically generated one) in an email on registration.
It’s painless to use password resets
Ya and have they send you the (one-time) password in cleartext
Well, the tokenized link is essentially a clear text one time password. Not really any better than just a one time password except for the convenience that the user does not need to type it in. If someone gets hold of the link or password before you they can get access to your account.
(one-time)
You make it sound like an irrelevant detail, but that’s kind of the key part. If implemented properly, it’s only valid once and for a short period of time, which greatly reduces risk.
