Treat the Cash App settings as three different tools. Security Lock adds a face, fingerprint or PIN check before payments, a card lock restricts the card, and sign-in or account-change alerts tell you about activity. None of them is a blanket block on every transfer type, and none guarantees a reimbursement.

Map the three controls before you change anything
When someone sends an unwanted financial request, the instinct is to flip one switch and assume you are covered. Cash App splits these protections: Security Lock requires face, fingerprint or PIN for payments, while card locking and sign-in or account-change alerts are separate controls. Review each one on its own terms so you know which action you are actually taking. [Cash App: support, payment and security controls]
- Open the app settings and note the current state of payment authentication, card lock and alerts before editing.
- Write down what each change is meant to stop, in your own words.
Security Lock applies to payments, not to everything
Security Lock is a payment-authentication step. It is designed to require a face, fingerprint or PIN before payments proceed, which helps if someone else has your unlocked phone or is pushing you to send money quickly. It is not a promise that every type of transfer or account action is blocked, so do not treat it as a universal barrier. If a control you expected is not visible in your app, record it as unavailable and stop at that access boundary rather than guessing a menu path. [Cash App: support, payment and security controls]
| observation | limit | next step |
|---|---|---|
| A payment-auth prompt appears for a send action | Does not by itself cover other transfer types or account changes | Check card lock and alerts separately, then decide |
| The setting you want is not shown in your app | Availability can vary by interface or region | Mark it unavailable and use official current help |
Card locking is a card-level action
Locking a card is a distinct control from payment authentication. It restricts the card rather than acting as a master switch over every movement of money in the account. Think of it as one layer that may be useful if the card itself is the concern, and keep expectations narrow: a card lock should not be described as blocking every transfer type.

Alerts are detection, not prevention
Sign-in and account-change alerts are informational. They can tell you that something happened, but they do not stop a payment from being sent and they are not proof that an account is safe or compromised. Read an alert as a prompt to review activity through the provider's own app, not as a verdict about who did what. [Cash App: support, payment and security controls]
- Turn on alerts you can act on, and check where they arrive.
- If an alert surprises you, review activity in the app before responding to anyone.
Reports and reimbursement are not the same
Cash App offers in-app reporting, and reports can be investigated. Reimbursement depends on claim eligibility, so no one should promise you a refund, and you should not assume that filing a report restores the money. Keep messages and records of the request and use the app's own reporting path. Support will not ask for your sign-in code or PIN; if someone does, that is a reason to stop engaging through that channel. [Cash App: support, payment and security controls]
A hypothetical sequence for an unwanted request
Suppose, hypothetically, a stranger messages you asking for money and pressures you to act fast. A calm order is: decline to send anything, do not share codes or your PIN, then review payment authentication, card lock and alerts one at a time in the app, and report the request in-app if appropriate.

A couple more questions
Does turning on Security Lock stop every transfer?
No. Security Lock requires a face, fingerprint or PIN for payments, but card locking and alerts are separate controls, and it should not be described as blocking every transfer type.
If I report a request, will I get my money back?
Reports can be investigated, but reimbursement depends on claim eligibility. No one should promise a refund.
Will Cash App support ever ask for my sign-in code or PIN?
Cash App says support will not ask for a sign-in code or PIN. Treat such a request as a reason to stop and verify through the app.
