What integrations do you have in mind?

There is a set of must-have integrations for customer-facing apps, like login with social media accounts which we support. However, for the enterprise apps is more important to provide the SSO integrations to facilitate the on/offboarding processes. For all apps that use certain kinds of financial integrations, it became the market standard to offer the KYC and KYB processes that enhance the user identification process.Embedded finance
