Login, recovery and MFA
Use your supported sign-in method for the intended account. An already linked Google method may be usable; Google controls its own account recovery. External sign-in is not a local password identity. Stop repeated password guesses and follow displayed error guidance. For eligible local-password recovery choose Forgot password? and use the newest recovery code privately. If recovery contact/method is unavailable, ask your administrator/support to assess eligibility without sharing codes/passwords.
Open Security to set up or turn off Authenticator App (time-based code) two-step verification. Email two-step verification is not currently available. Use the configured method; enabled membership does not prove a password works or invitation arrived. Do not bypass a challenge or infer temporary-password expiry from account dates.
API key access and revocation
Open Developers → API Keys. Keys are account-scoped and production runtime-scoped; plaintext is shown once. Store it privately in the integration's secret store. Inspect active/revoked status and scopes. fax:send/fax:read are the normal sending/reading baseline; choose broader scopes only for a demonstrated integration need, not to bypass a forbidden response.
If a key is exposed, an authorized key manager should revoke it, verify revoked state and replace it safely in the integration. Delete only after revocation where supported. Reconcile uncertain sends before repeating them. Never send the key or Authorization header to support. Use https://docs.faximus.io/ and https://api.faximus.io/openapi.json for current customer fields/scopes/upload/send/idempotency contracts; this article does not duplicate the API specification.
Safe support details
For help, open Help in your signed-in Faximus account and copy support details. Provide only the page, request or fax reference if shown, approximate time/timezone and expected versus observed behavior. Do not share fax contents, medical details, passwords, verification codes, API keys, payment details, document links or raw logs. Support may need independent identity/account verification.
