Frequently asked questions

What happens if I forget my master password?

All data encrypted with that password becomes permanently inaccessible. We cannot reset or recover it for you, so make sure you always remember it.

How does IronCrypto encrypt my data?

Your master password is turned into an encryption key on your device using PBKDF2, and your data is encrypted with AES-256 in Galois/Counter Mode (GCM) before it is sent to our servers.

Why encrypt and decrypt my data on my browser/device?

By encrypting everything on your browser/device and never sending your master password to our servers, we can ensure that your data is always encrypted and nobody, including us, can decrypt it. Even in the unlikely event of a breach to our servers, your data would remain securely encrypted to anyone that does not know your master password.

Why is Google or Apple sign-in required?

Signing in with an existing Google or Apple account verifies that you are a real person and acts as a first layer of protection. To reach your passwords, someone would first need access to your Google or Apple account, which may itself be protected by two-factor authentication, and would then still need to know your master password.

How do I delete my account?

Sign in, open the Account page from the sidebar, and click Delete Account. This permanently removes all your data from our servers; it cannot be recovered.

IronCrypto is a password manager built around one idea: your data is yours alone. You sign in with your Google or Apple account, then create a master password that never leaves your device. Everything you store is encrypted in your browser with that master password before it is sent to our servers, so neither IronCrypto nor our hosting providers can read it. Labels keep your vault organized, and secure sharing lets you hand a password to family or friends without ever exposing it.

One master password unlocks and encrypts everything, on every platform you use.

Secure

AES-256 encryption runs on your device before any data reaches our servers, which run on Google Cloud for reliability and performance.

Convenient

Available for iOS, Android, and any modern web browser.

How does IronCrypto encrypt my data?

Your master password is turned into an encryption key on your device using PBKDF2, and your data is encrypted with AES-256 in Galois/Counter Mode (GCM) before it is sent to our servers.

Why encrypt and decrypt my data in the browser?

Because your master password never leaves your device, your data is stored in a form nobody else can decrypt. Even in the unlikely event of a breach of our servers, your passwords would remain unreadable without your master password.

Why is Google or Apple sign-in required?

Signing in with an existing account verifies that you are a real person and acts as a first layer of protection: someone would need access to your Google or Apple account before they could even attempt your master password.

How can I import or export my passwords?

Import and export are available here on ironcrypto.com: open the Account page from the sidebar and choose Import Passwords or Export Passwords.
