Why Passwords Are a Security Risk
Traditional passwords create vulnerabilities that attackers exploit every day.
Password Reuse
People reuse passwords across dozens of websites, creating cascading breach risks.
Phishing Attacks
Hackers steal credentials through sophisticated fake login pages.
Credential Stuffing
Leaked passwords allow attackers to access many accounts simultaneously.
Password Fatigue
Users struggle to manage dozens of complex passwords across services.
Over 80% of breaches involve stolen passwords.

QR Login FAQ
Common questions about the security of QR code authentication.
Yes. LogMeOnce QR codes are secure, protected codes — not normal QR codes. Each one is generated automatically, encrypted, valid for a single login session only, and expires after a short time, so it cannot be copied, reused, or replayed by an attacker.
No. Because every QR code is one-time use and time-limited, a screenshot or photo of it becomes useless within seconds. Authentication is also bound to your trusted device, so the code alone is never enough to log in.
No. Simply scan the secure QR code with the LogMeOnce mobile app and confirm on your phone — no password is ever typed, transmitted, or stored on the device you are logging into.
LogMeOnce offers secure backup options such as biometric login and selfie authentication, so you are never locked out when QR scanning is not an option.
