About this extension
🔐 GESLAR — Free Password Manager from Croatia
Geslar is a completely free password manager that keeps all your passwords, cards, and TOTP keys encrypted on your device. No cloud. No account. No tracking.
🆕 NEW IN v2.5.8: IN-PAGE GENERATOR, AUTOFILL ON REDDIT
• Click a password field to open a generator overlay — fill without copy-paste
• Toggle passphrase/password, regenerate, auto-fill the confirm field (green outline confirmation)
• Autofill now works on Reddit and web-component login forms (open shadow DOM)
• TOTP QR paste — Ctrl+V a QR image from clipboard in TOTP setup (bypasses popup-closing on drag)
• TOTP QR drag directly from Google/GitHub/GitLab 2FA setup pages
✅ WHY GESLAR?
