Go to supplier.coupahost.com and in the Log In pane on the right, enter your email address and password and click Log In.
Once you are signed in, Coupa takes you on a tour of the new site.
When you log in for the first time, you are prompted to enable two-factor authentication. See Enabling or Disabling Two-Factor Authentication for more info.
Some customers may require you to use two-factor authentication when accessing their information.
Logging in with Two-Factor Authentication
If you have enabled two-factor authentication, the Two-Factor Authentication window opens when you log in to the CSP.
Open Google Authenticator on your device and choose your CSP account. Get the number that's shown.
Type the two-factor authentication code in the appropriate field, choose Remember this computer for 30 days if you're not using a shared or public computer, and click Log In.
The code that Google Authenticator provides is good only for 60 seconds. If you don't type that code on the CSP sign-in page and click Log In within 60 seconds, you have to get a new code and try again.
See Enabling or Disabling Two-Factor Authentication for more info.
If you are locked out and you don't have your six-digit backup validation code, contact your customer who will ask for a declaration form and either your email used to log in to the CSP or a copy of your photo ID or passport to verify your identity.
