We’ve changed how you log in to CSBOS to keep your information safe.
You now need to set up Multifactor Authentication (MFA) with a passkey or an authenticator app to access your CSBOS account.
While you set up your passkey or authenticator app, you can still log in using a One Time Password that we’ll send you.
After June 2026, you won’t be able to use One Time Passwords for CSBOS. It’s important to set up MFA before then.
