QuietPass SMS verification terms

Who sends the text

What you are requesting

After verifying your email, enter a number you own and check the SMS acknowledgment to request a six-digit phone verification code. We record the acknowledgment and its version. A resend is another request and requires another acknowledgment. These messages help confirm access to your supplied number; they do not contain advertising or messages sent on behalf of lookup customers.

One message per request. Message and data rates may apply. QuietPass does not charge your wallet for the verification text. Your mobile provider may charge for sending or receiving messages.

Help and opting out

Where reply-enabled SMS is supported, reply STOP to opt out or HELP for help. US verification texts are sent from +1 201-374-4492 with STOP and HELP replies enabled. For other destinations or senders that cannot receive replies, contact hello@quietpass.com for help or to withdraw your request.

After an opt-out is processed, further verification texts must remain blocked until the provider-supported re-enrollment process is completed. Checking the website acknowledgment again does not override a provider opt-out. Contact support for help. STOP and HELP may generate a confirmation or help reply in addition to a requested code.

Availability and your account

SMS verification depends on destination coverage, sender registration, price and security limits, and delivery by mobile networks. Where we cannot send a text, you can use the alternative onboarding journey. You may continue signing in by email, Google, or a saved passkey where available.

Carriers are not liable for delayed or undelivered messages. Codes expire after five minutes. You can request up to three verification texts for your account, with at least two minutes between requests. Changing numbers does not reset this allowance. Additional service-wide limits can also apply. Do not share a verification code.

Your information

We use your number to deliver requested verification texts and provide the preview described in the phone setup flow. SMS delivery providers process information needed for delivery and security. We do not sell or share mobile information or SMS opt-in consent for marketing or promotional purposes. See our privacy notice and data handling information.

These terms apply to verification requests made with the SMS acknowledgment version sms-verification-2026-10-23. They supplement the service terms for that request and do not change an earlier service agreement.
