New Customer Accounts: “Unavailable” page with 59-second auto-reload after repeated OTP requests

During automated testing of Shopify New Customer Accounts, repeated OTP generation requests eventually result in an “Unavailable” page with an 59-second auto-reload countdown instead of the OTP entry screen. Has anyone observed this behavior? Is it a documented customer-account rate-limiting mechanism, and are the limits based on email, IP, device fingerprint, or a combination of factors?

Observed during Playwright automation and manual validation

Hey @Kumaran_Periyasamy what you are describing does sound like standard anti-abuse behaviour. There’s no documentation on limits here so I would recommend to distribute your tests across distinct email addresses and add reasonable delays between login attempts.
