About this extension
Locker is a cross-platform vault that help users secure sensitive digital assets such as logins and passwords, secret notes, payment cards, online identities, and crypto wallets. It also offers additional features to enhance browsing experience like password autofill, item sharing, and more.

Why choose Locker over other password managers?

1. Security
- Locker uses military-grade encryption to secure your data. AES-256bit encryption combined with PBKDF2 and RSA algorithm makes your data is un-crackable.
- Your vault is encrypted with a Master Password, which is the only key to decrypt your data.

2. Privacy & Transparency
- Your Master Password is only yours. No body, even us, can see your Master Password thanks to Zero-knowledge development model.
- Locker is an open-source product. Everyone can inspect its source code. We believe transparency is the key to better security.

3. Unlimited Sync
- Once you add, edit, remove items in your Locker on a device, the data will be sync-ed across all other devices*.

4. Bring Your Passwords with You
- With Offline Mode, you can use Locker anywhere, anytime, even when your phone is not connected to the internet**.


No more password hassle.
Free Your Mind. Install Locker.

*Data is encrypted before they left the current device.
**Offline Mode is only available on Locker mobile application (Android & iOS).
