AWS has now resolved the issue with their infrastructure, and email logins are back functioning normally once again.

Because of an issue with AWS, signing into Unito (or signing up) with email/password is currently unavailable. Signing up/in with one of our partner apps is still working normally.
We'll update our status page as soon as AWS sends out an update.
