Random BIP39 mnemonic phrases of 12 or 24 words for cryptocurrency wallets
A seed phrase generator creates a BIP39 mnemonic phrase — a sequence of words used to back up and restore a cryptocurrency wallet. The seed phrase is the master key to your funds, so it must be generated from a truly random source and kept strictly secret.
The tool is useful for learning how crypto wallets and the BIP39 standard work, and for demonstrations and testing. The phrase is generated locally in the browser and is not transmitted or stored. Never use a phrase from any online tool for a real wallet holding funds.
Choose the number of words (12 or 24) and press the generate button. Copy the ready phrase with one click or generate a new one. For real assets, always generate the seed phrase offline on a trusted device.
