What is diceware-style randomness?

Words are chosen from a fixed list using cryptographically secure randomness so each pick has equal probability. More words multiply the search space exponentially.

How many bits of entropy do I need?

Aim for at least 128 bits for master passwords or disk encryption. Fewer bits may suffice for secondary secrets but avoid going below modern password-manager recommendations.

Are passphrases safer than passwords?

Long random passwords and long random passphrases are both strong when entropy is high. Passphrases can be easier to type if you avoid predictable phrases or lyrics.

Should I add numbers or symbols?

Extra characters help only if they increase unpredictability. Random separators or an extra word usually beat keyboard-pattern ornaments.

Can I memorize these without a manager?

You can, but a password manager remains safer for dozens of accounts. Use memorable passphrases mainly for the vault master password or device logins you must type often.

Will every site accept long passphrases?

Some legacy systems cap length or forbid spaces. Keep a fallback generator handy and avoid truncating phrases yourself.

Is anything sent online?

No. Random draws execute locally; generated text never leaves your session unless you copy it.

Why not reuse one passphrase everywhere?

Credential stuffing breaks that pattern instantly. Generate unique secrets per account and store them in a vault.
