Crypto security: secure the account, protect the keys
Set up stronger authentication, make a recoverable wallet backup, and recognize the requests that put your crypto at risk. Practical guides for exchanges, hardware wallets and DeFi.
Start with account access and recovery. A secure device cannot protect a seed you enter into a phishing form.
Set up two-factor authentication for your crypto accounts
Choose a security key or authenticator app, save recovery codes, and secure the email account that controls your exchange logins.
Set up a hardware wallet without exposing your backup
Check the device, install official software, create and verify the backup, then test a small transfer before moving a larger balance.
Back up your wallet so loss and theft are both covered
Choose offline storage, verify the backup, plan for fire and theft, and understand how a passphrase changes recovery.
Recognize crypto phishing before you sign or send
Spot fake support, login pages, wallet updates, investment pitches and recovery scams. Know what to do after a suspicious request.
Use DeFi with a clear limit on what you can lose
Understand token approvals, contract and bridge risk, audit limits, and how to separate experimental funds from long-term holdings.
Secure an exchange account and understand custody risk
Review authentication, withdrawals, API permissions, the legal entity holding your crypto, and what protection applies to each balance.
Build a password-manager setup you can recover
Use unique passwords, protect the vault, separate high-value second factors, and keep a recovery plan that survives a lost device.
Keep a phone-number takeover from becoming an account takeover
Reduce reliance on SMS, protect carrier-account changes, and know the first steps to take if your number is transferred without permission.
