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.

This application offers a convenient auto-fill password feature. I would appreciate the ability to utilize it offline, as it currently necessitates an internet connection for each use. Additionally, I've observed that opening mobile application redirects to the password section, preventing access to other functionalities such as my card details or personal informations etc...

The Locker password manager is a fantastic system, highly recommended. It works well on windows & Linux but the android version is very buggy, it's very slow to load & keeps giving "app not responding" error. If you tell it to wait it will eventually load after a minute or so. Not very good if your in a hurry. This review is just for the android app part of the system, the rest of it, web\win\linux is well worth paying for. Please can the Devs sort out the android app.
