Not sure how widespread this is, but last night and still this morning I am seeing that there is a sign-in issue on PSN. Upon attempting to sign in, users are told they must reset their password. At that point, the link in the e-mail or password (not sure which) do not work, basically locking the user out of PSN.

Following @AskPlaystation, they do not seem to think there is an issue but reading mentions indicates a different situation. I do not know if this issue is happening on PS3.

Anyone run into this? I'm staying off my PS3/PS4 until I know it has been rectified.
