About this app

Locker is a cross-platform vault that helps users secure sensitive data such as logins and passwords, secret notes, payment cards, and online identities. It also offers additional features to enhance your browsing experiences 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 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. Nobody, even us, can see your Master Password thanks to Zero-knowledge architecture and End-to-end encryption.
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, or remove items in your Locker on a device, the data will be synced across all other devices.

4. OTP is integrated right into the app
Protect your online accounts with an extra layer that is integrated right into Locker. One-time password (time-based) enables you to block hackers from accessing your accounts even when they've got the passwords. Let's open 2FA (two-factor authenticator) in your critical accounts and start using our authenticator feature.

5. 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 leaving the current device.
**Offline Mode is only available on Locker mobile application.

It is fast and no issue when login on IOS. For android (I am using Oppo Find X 8) login so slow and now unnable to login with pop up "Network Error. Your connection is not secure".

The app crashes every so often and it takes a lot of battery. The very basic features works OK.

Thanks to the company CyStack (locker.io), my personal data, including passwords, benefits from enhanced security. CyStack has a strong and transparent commitment to protecting the data of its product users. It is a very accessible and open-source password manager with modern and high-level security features. Thanks to the CyStack security team, congratulations on the protection of the confidential data represented by Locker CyStack.
