# Update freight provider account credentials

Replace the credentials stored for a freight provider account — the mechanism for rotating a client secret without disconnecting.

The new credentials are verified against the provider before they replace the stored pair, so a failed verification leaves the existing connection working. The connection's nickname and account number are untouched.
