PSN Password Reset Emails ‘Expire After 24Hrs’
PSN access requires a mandatory password change (courtesy of update 3.61) which sends an automated email confirmation to users.
"Just been checking the latest on this and there is still a huge backlog of emails with the ISP and waiting to go through," blog manager James Gallagher wrote today.
"All we can say is please wait and they will all go through as the massive demand eases. However, if you have been waiting for more than 24 hours than it may be worth submitting a new request now, as each email has a 24-hour expiry. Just be sure to only submit the request once."
