Secure all sign-ins
from any device
Privacy Guardian is a password manager that encrypts your passwords before they leave your device. Use the Overwatch dashboard to see your security score, breach alerts, weak and reused passwords, and a built-in password generator. One master password—autofill everywhere.
Your security at a glance
Overwatch gives you one place to see your security score, password strength, and what to fix—from data breaches and weak passwords to reused logins and sites where you can add 2FA or passkeys.
How it works
Create your vault
Sign up with email and choose one master password. Your master password never leaves your device—we never see it, store it, or transmit it.
Add your passwords
Save logins as you browse. When you log in to a site, we offer to save it. Or add entries manually. Everything is encrypted before it's stored.
Fill and go
Unlock the browser extension with your master password. Click Fill on any saved login to autofill username and password. Done.
Password management built for privacy
From passwords and login credentials to breach alerts and a built-in password generator—keep everything in one place and know exactly what to improve.
Overwatch security dashboard
One score, one view. See your overall security health, overall password strength bar, and actionable cards: data breaches, reused passwords, weak passwords, unsecured sites, passkeys available, and 2FA to set up.
Data breach monitoring
Check your account email and vault usernames against Have I Been Pwned. Get a dedicated Breaches page with expandable lists and full breach details so you know what was exposed and when to change passwords.
Password generator
Create strong random passwords or memorable passphrases. Choose length, character types, avoid ambiguous characters, and see strength before you save. One click to copy into your vault.
Weak & reused password alerts
We flag entries with strength below 60 and detect when you reuse the same password across sites. Open and save an entry to refresh its strength; use the vault filters to see weak or reused items and fix them.
End-to-end encryption
Your vault is encrypted with AES-256-GCM before it ever reaches our servers. We cannot read your passwords—only you hold the key. Your master password is used to derive an encryption key; it is never stored or transmitted.
Browser extension autofill
Install the Privacy Guardian extension for Chrome or Firefox. Unlock once per session and fill any saved login with one click. Works on virtually any site. Auto-fill when you have a single match, or pick from your list.
Save as you log in
When you successfully log in to a new site, we prompt to save it. No need to remember to add it later. The extension appears right after login—even after the page redirects—so you never miss a save.
Organize with folders
Group logins into folders—Work, Personal, Banking, Social—and filter by folder in your vault. Keep hundreds of passwords organized without scrolling forever.
One master password
Remember one strong password. We take care of the rest. Use "Keep unlocked for this session" in the extension to avoid typing it repeatedly. Lock manually when you step away.
Web and extension
Manage your vault in the web app—add, edit, delete, search. Use the extension for quick fill and save. Same encrypted data, synced everywhere. More platforms coming.
Why use a password manager?
Data breaches, phishing, and weak passwords put your accounts at risk. A password manager is the simplest way to stay secure.
Prevent account takeovers
Billions of passwords are exposed in data breaches every year. When you reuse the same password across sites, one leak can unlock your email, bank, and social accounts. A password manager lets you use a unique, strong password for every site—without memorizing them.
Stop password fatigue
The average person has over 100 online accounts. Reusing weak passwords like "Password123" or slight variations makes you an easy target. Password managers generate and store complex passwords for you.
Protect against phishing
Phishing sites mimic real login pages to steal your credentials. A password manager only autofills on the real site you saved—it won't fill on fake copies. Even if you click a malicious link, your credentials stay safe.
Simplify your digital life
Strong passwords are long and random—impossible to remember across dozens of sites. With Privacy Guardian, you create one master password, and we handle the rest. Autofill, search, organize. Never type a password again.
Security and privacy by design
We built Privacy Guardian so you never have to trust us with your secrets.
Zero-knowledge encryption
Your master password and encryption key never leave your device. We use PBKDF2 with 310,000 iterations and AES-256-GCM. Even if our servers were compromised, attackers could not decrypt your vault.
No tracking, no ads
We don't use analytics, advertising, or third-party trackers on our service. Your vault data is encrypted. We store only what's needed to sync your encrypted vault across devices.
You own your data
Your passwords are yours. We don't sell, rent, or share your data. Delete your account anytime and your data is removed from our systems. Read our Privacy Policy for full details.
