What crypto app doesn t require ID?

I'm curious to know if there are any cryptocurrency apps available that do not require users to provide personal identification, such as a passport or driver's license, in order to create an account or engage in transactions. I understand that many crypto platforms require some form of verification for security and regulatory purposes, but I'm looking for an alternative that allows for more anonymity. Can you recommend any crypto apps that do not have this requirement, and if so, what are the potential risks and limitations associated with using them?
