If you originally signed up through Facebook and are currently logged into Picmonic, you can change your email from your Profile page, and must change your password from your Site Settings page.
Changing these details will allow you to log in with whatever you set your email and password to instead of Facebook.
If you aren’t able to log in, reach out to us via feedback@picmonic.com or through the chat widget and we can help reset your email address/password so you can log in any time without going through Facebook!
