If you forgot your password and can't log in to Qualys then get in touch with somebody in your organization with a Manager role (or Unit Manager if your account is part of a business unit) and ask them to reset it following the steps below. An email will be sent to you with new credentials and you'll be back in business.
Step 1: Go to the Users List
Log into Qualys and go to Users > Users.
Step 2: Edit the User's Account
Find the user’s account (search and filter options may be helpful in large subscriptions) and choose Edit from the Quick Actions menu.
Step 3: Click Change in the Security Section
On the Edit User page, click Security (on the left side). Then click Change under Password. An email will be sent to the user with new login credentials.
