Frequently Asked Questions
What is a passphrase and how is it different from a password?
A passphrase is a sequence of words or a sentence used for authentication, typically longer and more memorable than traditional passwords. While passwords often use random characters, passphrases use real words making them easier to remember yet more secure due to their length.
How secure are passphrases generated by this tool?
Our passphrases are generated using cryptographically secure random methods. A 4-word passphrase has over 1.6 million possible combinations, while a 6-word passphrase has over 1.6 billion combinations, making them extremely difficult to crack.
How many words should I use in my passphrase?
We recommend 4-6 words for most uses. Four words provide excellent security for most accounts, while 6+ words are recommended for high-security applications like cryptocurrency wallets or encryption keys.
Should I add numbers and symbols to my passphrase?
Adding numbers and symbols increases security but may reduce memorability. For most users, a longer passphrase with just words is more secure and practical than a shorter one with special characters.
Is this passphrase generator safe to use?
Yes, absolutely! All passphrases are generated locally in your browser using secure random methods. No data is sent to our servers, and we never store or log any generated passphrases.
Can I use these passphrases for cryptocurrency wallets?
While our passphrases are secure, cryptocurrency seed phrases have specific requirements (usually 12-24 words from a specific wordlist). Use wallet-specific tools for generating crypto seed phrases.
How do I remember a long passphrase?
Try creating a mental story or image connecting the words, or use the first letter of each word to create an acronym. Practice typing it a few times, and consider writing it down initially while you memorize it.
Should I use the same passphrase for multiple accounts?
No, never reuse passphrases across multiple accounts. Generate a unique passphrase for each important account, and consider using a password manager to store them securely.
