Deadlock is your all-in-one digital security toolkit. Scan your email for data breaches, check password strength, verify QR codes and URLs before opening them, and analyze your Wi-Fi network security — all in one app. - Email Scanner Enter your email address and instantly find out if it appears in known data breaches. See which companies were compromised, what data was exposed, and get step-by-step remediation guides to secure your accounts. - Password Checker Test any password's strength with real-time crack time estimates. Check if your passwords have been found in breach databases using the Have I Been Pwned API.
