# Security and Encryption For a browser extension platform like Realm, logging in using a cryptocurrency wallet provides a strong security architecture based on cryptography concepts. This method guarantees that user data is kept private and shielded from unwanted access by utilizing digital signatures, end-to-end encryption, and private key authentication. Integrating hardware wallet functionality, which stores private keys in safe hardware devices offline, substantially improves security and also keeps your identity anonymous. Realm offers options like wallet connect and coin base wallet (crypto wallets) as primary sign-in options apart from Google and Twitter. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
