You must sign up to Pixton using Single Sign On (SSO). You can choose to use Google, Microsoft or Clever. All of these methods use OAuth2.0, the industry-standard protocol for authorization.
Single sign-on (SSO) lets you log into Pixton without having to keep a separate password. Also, if for instance you use SSO with your Google, Microsoft or Clever account, we have absolutely no way of knowing what your account's password is. SSO is a simpler and more secure way to log in, period :)
To sign in with a Google, Microsoft or Clever account, simply choose an account you are signed into or enter an email and password to sign in for the first time.
