Passphrases assist users in safeguarding account or cryptocurrency wallet access, which need to be kept private and confidential.
What is a passphrase?
To safeguard the user’s private key or encrypted wallet account, a passphrase—also referred to as a seed phrase or recovery phrase—is a combination of letters, numbers, and special characters. Recovery phrases, in contrast to private keys, frequently have a longer capacity and might contain words to generate secure passwords, making it more difficult for hackers to employ brute force attacks (password guessing attacks).
In order to aid users in recovering their accounts in the event that they forget their password or wish to reinstall the wallet on a different device, the majority of cryptocurrency wallets employ a seed phrase consisting of 12 or 14 random syllables. Therefore, in order to prevent losing their cryptocurrency holdings and personal data, investors must securely store their password and not divulge it to third parties.
In 2016, the cryptocurrency recovery business Unciphered revealed a Randstorm passphrase vulnerability. When the business attempted to get the recovery phrase for investor Nick Sullivan, it found the mistake.
Accordingly, Randstorm only permits the generator to produce random recovery phrases from thousands of words, as opposed to producing seed phrases from millions of words. This facilitates the process by which hackers can quickly obtain the user’s passphrase and steal assets. Approximately 1.1 million bitcoin wallets experienced this issue, resulting in thousands of users losing their tokens.
