The One Rule
Nobody Legitimate Will Ever Ask for Your Secret Words
Support agents, banks, wallet makers and real apps will never ask for your password, recovery phrase or login codes. Anyone who does is trying to rob you.
Always Do
- Use a different, long, random password for every account.
- Turn on two-factor login for your email and bank first.
- Write recovery words on paper or steel, in private, and test the backup.
Never Ever Do
- Never type your recovery phrase into a website, app, chat or email.
- Never photograph your words or save them in cloud notes.
- Never share a password or code with someone who contacted you first.

Password, Recovery Phrase, Passphrase
Three secrets that look alike and behave very differently.

| Who can reset it | The website or service | Nobody | Nobody |
| Where it belongs | A password manager | Paper or steel, offline | Your memory and a separate backup |
| If it is stolen | Change it and get support | Move funds at once | Useless alone, but do not rely on that |
| Typed online? | Only on the real site | Never | Only on your own hardware wallet |
