Sign-in security best practices
When you sign in to any crypto account, apply multiple layers of protection. Start with a unique, strong password — ideally generated by a password manager. Add two-factor authentication for a second factor. Use biometrics on trusted personal devices to make sign-in fast while maintaining security. Finally, keep a secure, offline backup of recovery secrets (if your account uses seed phrases) and never share them online.
Actionable checklist
- Create a unique strong password using a password manager.
 - Enable 2FA (authenticator app or security key preferred over SMS).
 - Set up biometric unlock on mobile for convenience with security.
 - Regularly review and revoke unused devices and active sessions.
 - Keep software and device OS updated to avoid known vulnerabilities.
 
Balancing speed and security
Secure sign-in doesn’t have to be slow. Use password manager autofill, biometric unlock, and SSO with trusted identity providers (for enterprise or partner integrations). Keep long-lived sessions for trusted personal devices, but have short session lifetimes for public or shared devices. These strategies let you access your crypto quickly while maintaining a robust security posture.
// Example: show stored session warning (pseudo)
if (session.fromPublicDevice) {
  alert('You are signed in from a public device — consider using private mode.');
}
      Frequently Asked Questions
How can I sign in securely to my crypto account?
Use a unique strong password, enable 2FA (authenticator app or hardware key), verify you are on the official secure HTTPS site, and avoid public Wi-Fi for sensitive sign-ins.
What is the best 2FA option for crypto?
An authenticator app (TOTP) or a hardware security key (FIDO2) is preferred. SMS is better than nothing but is less secure due to SIM-swapping risks.
Can I use biometric login?
Yes — biometrics (FaceID or fingerprint) are a convenient and secure option on trusted devices, especially when combined with device-level encryption and 2FA.
What should I do if I suspect unauthorized access?
Immediately change your password, revoke active sessions, disable linked devices, and contact support. If funds may be at risk, move assets to a new secure wallet after regaining control.
How do I speed up sign-in without sacrificing security?
Use password managers for autofill, enable biometrics on trusted devices, and use SSO for enterprise identities while keeping 2FA enabled for critical actions.
