Hi,
I have a client who has decided to add the ability for external users to submit bank account information through a Power Pages site. Before that decision the plan was to use Azure AD B2C which is the recommended approach for external authentication. My question is, what is the recommended approach for handling bank account information? They have an application form people will be filling out that includes bank account detail and while I know Azure AD B2C is secure, what additional security considerations do I need to be aware of or is there an additional layer of security recommended in this case?
