What is Santander Key and what is it for?

Santander Key is an omnichannel, multi-product signature solution that you can use to sign all of your transactions from your mobile phone. You confirm any purchase with your fingerprint or Face ID as the validation method. Forget about passwords and start paying quickly and safely!

Santander Key uses biometrics to strengthen authentication processes and, therefore, reduce the possibility of fraud.

How does Santander Key work?

When you shop, you receive a confirmation notification on your mobile phone. Tap the message to open the app and confirm the purchase through the fingerprint recognition sensor, or Face ID. Simple and practical! You can also tap on the Santander Key button, at the bottom of the app's home screen, to view any transactions pending confirmation.

Why is it important to have Santander Key?

Your security is our top priority and, for that reason, we have created Santander Key. This method is really important because it reduces your risk of becoming a victim of fraud when you shop online. Cybercriminals find it easier to seize access details based on keys or passwords than on biometric data. Santander Key uses biometric data to operate: you authorise all your transactions from your device, and have control at all times.
