I'm having problems with my electronic signature and can't use my accounts

If you've forgotten your electronic signature, or if it's been blocked, you can request a new one. Log in to Online Banking using your password and select "Personal Area" from the top menu. Head to "Security" and click on "Electronic signature sent to your home". We will then send you a new electronic signature by post to the address linked to your multichannel contract.

You can also request a new electronic signature by contacting Superlínea. The automatic system will identify you and will send you an electronic signature by SMS or, if you prefer, by post to your home address.

Remember that the electronic signature you receive by SMS or by post is temporary and you will need to activate it via the app or online banking by following a few easy steps.
