Frequently Asked Questions
What is BIP39?
BIP39 (Bitcoin Improvement Proposal 39) describes the implementation of a mnemonic sentence—a group of easy-to-remember words—for generating deterministic keys. It is widely used in crypto wallets as a backup/recovery phrase.
Are my generated mnemonics secure?
Yes. Mnemonics are generated client-side using standard cryptographically secure random values (`crypto.getRandomValues`) mapped to the official English BIP39 wordlist. No data is sent over the network.
