Security, passwords and protecting your company

Passwords and codes stay with you

• Do not give your bank password, PIN, token, authentication code or full card details in messages or on this page.
• Do not install remote access apps at the direction of an unverified contact.
• Check the recipient and the details of each operation before confirming.

Lost access or changed phones?

Use only the responsible institution's official recovery process. Each bank defines its own steps and may require a new device enrollment. Tecbank does not enable banking identifiers and does not receive your codes.

Stolen phone or suspected fraud

Contact the bank's official channels immediately to report the incident and request protection for your access. Also ask your carrier to block the line. Change passwords through official channels on a trusted device and keep the reference numbers.

Access control in the company

Do not share the administrator's access. Review users and permissions in the bank's official channels, remove access that is no longer needed and use the approval mechanisms available in your contract.

Received a suspicious purchase alert?

Treat the message as a notice to verify, not as proof that the sender is the issuer. A name, photo, badge or the look of a conversation does not replace checking through the official channel.

1. Check the purchase: open on your own the app already installed or the issuer's channel you know. Compare the amount, date, merchant and the card used.
2. If you recognize it: confirm only in the official flow indicated by the institution. Do not give your password, token or security code to whoever contacted you.
3. If you do not recognize it: use the issuer's official channel to protect the card and register the dispute. Keep the reference number and follow the next instructions.
4. If you are unsure about the message: do not follow the link or call the number received in it. Find the contact verified in the app, the contract or on the back of the card.

Do not make a Pix, transfer or payment to an alleged safe account. Do not install a remote access app or hand over your card at the direction of an unexpected message.

Tecbank does not confirm purchases, does not block or unblock cards and does not receive banking disputes in this guide. An alert or block does not mean a purchase has already been reversed; confirm the situation with the issuer.

Organize your business account security

In your bank's official app, learn about the authentication features, card blocking, limit management and prevention guidance available for your contract. Do this check before an emergency.

If the device or the card is at risk, contact the official channel to request protection and record the reference number. A feature listed by the bank does not mean the block has already happened: check the confirmation and the next steps.

This is public guidance for visitors. Tecbank does not offer a banking blocking center, does not enable authentication and does not manage limits on this page.

Requests for money and codes over WhatsApp

Names, photos and logos can be copied. An urgent request does not prove who wrote it.

• A known person with a new number: confirm through a number you already had before transferring. Do not rely only on the contact sent in the message itself.
• An alleged security center: do not make a Pix to a "safe account" and do not pay to cancel a purchase. End the contact and reach out to the institution on your own initiative.
• Registration code and PIN: do not share the code received by SMS or the two-step verification PIN. Enable this protection in your account settings in the app.
• Video and documents: do not do an alleged proof of life or send biometrics and documents through an unexpected contact. Check the procedure in the responsible official channel.

If a transfer or improper access has already happened, contact the institution and the app's official support immediately. Keep records of the conversation and transactions without publishing your data. Recovery of funds depends on the responsible parties' analysis and is not guaranteed.

This is a public precaution for visitors. Tecbank does not request banking codes and does not execute blocks or disputes through this guide.
