• As a supplier I'm receiving the password reset email, but after update the password I'm not able to login in the account
• The login page redirects to another login page.
• I'm using the right credentials to login but still receiving the error: "The username and password pair you entered was not found."

• You are using a wrong login url, usually coming from an event invitation email
• Your browser is overwriting the username or password after your enter
• You have multiple accounts and you are updating the password from one username account but trying to login in a different one
• Your company firewall is blocking the Ariba connection

• After update your password and receive the message that your password has been updated, please avoid any invitation link and try to login with the regular Ariba login page: https://service.ariba.com/
• If still not working please open a different web browser and try to login.
• Check the username if is the same from the one that you updated the password and not from a different account, you can revise the right username during the password reset process.
• If your company have some firewall or restrictions, you can try from another device/internet connection to test if you can login in your account.

If you tested the regular login URL and now you can enter in the account, but still doesn't work with the event invitation, then your issue is a different one:

Why can't I find an event?
Error: The username and password pair you entered was not found
Why am I receiving an error saying the link has expired when trying to access a sourcing event?
Error: Log in with the username and password that you have used previously when you participated in sourcing events
Error: "Your company has already connected with this buyer company using a different account and SAP Business Network ID (ANID)..."
