Mnemonic Phrase Security

Definition

Mnemonic phrase security encompasses the practices and measures taken to protect a cryptocurrency wallet’s recovery phrase from unauthorized access. This includes safeguarding the physical or digital storage of the 12-to-24-word sequence, preventing phishing attacks that attempt to trick users into revealing it, and ensuring it is never stored on internet-connected devices. A compromise of the mnemonic phrase grants complete control over the associated digital assets, making its protection paramount. Robust mnemonic phrase security is the primary defense against asset theft in self-custodial scenarios.
