When you are logged into the Catalog Platform, you may reset your password by selecting the primary dropdown in the top left hand corner of the sidebar. Selecting this will open your organization selection screen and your user profile.
Select "account settings"
From there, you will be taken to a settings screen that includes information about your account, your API token, and password. Select the "password" button.
Provide and confirm your new password, then provide your current password. Select update to complete, and make sure you update your keychain with the new password.
If you have forgotten your password, you may sign out of the platform, then go through the "Forgot password" flow from the login screen.
