Service has been restored for all login services. We will continue to monitor this feature for any lingering effects over the coming days. Apologies to those affected.

We have identified the issue and implemented a fix. We are now working with our service providers to restore OTP based verification. New signups will be redirected to Google-based Sign Up

Email-based account creation (i.e. OTP Verification) is currently disabled as we investigate an issue. Google Authentication is unaffected.
