Private Keys & Seed Phrases
The single most important security concept in all of crypto.
What you’ll learn
- •A private key proves ownership and authorises transactions — keep it absolutely secret.
- •Signing a transaction proves you hold the key without ever revealing it to anyone else.
- •A seed phrase (12–24 words) can regenerate all your wallet's keys, so it's just as sensitive.
- •Never type, photograph, or digitally store your seed phrase anywhere online.
- •No legitimate support staff will ever ask for your seed phrase.
- •Lose both your device and your seed phrase, and there is no recovery mechanism at all.
