From the Okta End-User Dashboard you can change your password without having to contact an administrator.
If self-service password reset is enabled for your org, use the following instructions to reset your password if it has been forgotten.
In your browser on your computer type your Okta sign-in URL.
Click the Need help signing in? option at the bottom of the sign in panel, and then select Forgot Password.
Enter your work email address and click Reset via Email. An email should be sent to you with instructions and a link to reset your password.
Note: If you are part of an OIE org, you may have the option to use a different MFA factor to reset your password, depending on your org's settings.
