Webot's ACH bank connection runs through Stripe. This error appears when the bank authentication step does not complete — commonly because your bank uses a multifactor authentication method that cannot be completed during the connection.
Your bank shows its own message, and Webot's Deposit USD screen then shows: Failed — AUTHENTICATION_FAILED. Please try again or contact our customer service.
To connect your bank account, temporarily disable multifactor authentication on your bank account (not on Webot) and try again. Once the connection is complete, re-enable multifactor authentication with your bank. If the error continues, contact Webot Support.
