Verification and SSO handoffs

Verification (e.g. codes, authenticator) and single sign-on (SSO) handoffs can stall in a few common ways. Queries like 'fusebox elavon portal' often lead to these topics. This page covers what to check and what to avoid before escalating.

Code delivery delays

SMS or email codes can be delayed by carriers, filters, or queue. Wait the suggested time window (e.g. a few minutes) before requesting one resend. Do not request multiple resends in a row; that can trigger rate limits or blocks.

Authenticator time drift

Time-based one-time passwords (TOTP) depend on device time. If the device clock is wrong, codes may fail. Check that the device time and timezone are correct and synced (e.g. automatic time), then try again once.

Corporate IdP handoff

When sign-in goes through a corporate identity provider (IdP), the handoff can fail or show a blank page if cookies or redirects are blocked. Use the same safe checks as for sessions and cookies: allow site storage for the session, try once in a private window, and avoid repeated retries.

Device switching risks

Starting the flow on one device and continuing on another (or switching browser or tab mid-flow) can invalidate the session or cause loops. Prefer one device and one browser for the full flow. If you must switch, treat it as a new attempt and do not retry many times.
