# What is SCA and how can you validate it?

For transactions made before 16 January 2026, PasseTonBillet applied **SCA (Strong Customer Authentication)**, a legal requirement under European regulations.
It is designed to secure online payments and requires strong identity verification before any bank transfer.

### When do you need to validate it?

Only for transactions made before 16 January 2026.

SCA may be requested **only after you have sold a ticket**.
You do not need to activate it beforehand: everything will appear automatically in your profile after your first sale.

### How can you validate your SCA and receive your payment?

There are 3 steps:

1. **Validate your SCA**
A window will open automatically to confirm your identity through your bank, either via your banking app or by SMS.
It is quick, secure and required to receive your payment.
2. **Add your IBAN**
Once SCA has been validated, you can enter your bank account details for the transfer.
3. **Upload your ID**
This final step verifies that you are the account holder. It only needs to be completed once.

### Until these steps are completed, your payment will remain pending.
