Access is set up per company. If you sign in with an email address that is not yet linked to your company account, you land on a pending page instead of your contracts. Nothing is wrong with your password: the address just is not connected to an account yet.
Your Opkalla representative or your Technical Advisor can link it. Send them the exact address you tried to sign in with, since access is granted to an address rather than to a name.
Some people have access to more than one company account. When you do, an account switcher appears in the navigation, and everything you see follows the account you have selected: contracts, timeline, and budget.
