About this app

IronCrypto helps you keep all your passwords, payments and personal data secure and accessible through any device or browser. Our app is built around four tenets: Security, sharing, simplicity and accessibility.

Security
As a password management app, security is our number one priority and these are the steps we take to ensure it for all our users. IronCrypto encrypts all your data on your device with your own master password using AES 256. Your master password never gets transmitted to our servers and your data only arrives at our servers fully encrypted.

We utilize Google Cloud for our servers due to their high reliability, scalability and most importantly, security. Since all your data is encrypted when it arrives to us, even if there was a breach, your data would be perfectly safe from anyone that does not know your master password.

The fact that your data is completely obfuscated to us means that we cannot store or sell any of your data even if wanted to, and we are happy not to. Since we never compromise your security, we do not allow additional methods of authentication besides your master password, which means if you forget it, you will be unable to access your passwords.

Sharing
Need to share a password with a family member or colleague? IronCrypto lets you securely share passwords and files using RSA encryption. Only the intended recipient can decrypt what you send — we never see it.

Simplicity
IronCrypto is built with the belief that often times less is more and we pride ourselves in making our users' experience as fast and effortless as possible. Our app is built in such a way that you never have to tap too many times and select amongst dozens of categories to find or create a password.

In the passwords view you can see your passwords and search for specific ones using a password's title, url, username, password or notes. You can also filter passwords by label to view only passwords related to a specific part of your life such as work or shopping.

Adding a password is very easy and fast as we provide a small number of simple text fields that you can fill out (or not) in any way you see fit. All our text fields are encrypted, which means you can store any kind of information you want. IronCrypto can also generate secure passwords for your accounts so that you do not have to worry about coming up with unique, secure passwords all the time.

You can also apply labels to passwords to help organize them in any way that you find most convenient. Besides helping with organization, labels provide you with an additional visual aid that can help you find your passwords faster.

Accessibility
Security is a right not a privilege. You should not have to pay to keep your passwords safe. All you need is access to any browser or a device that uses the IronCrypto app. Users also need to have a Google or Apple account, which will act as a form of two factor authentication. For somebody to access your passwords, they would first need to hack your Google/Apple account, for which you may have separate two factor authentication, and then they would need to know your master password. This is why your master password always has to be unique, secure and you should never share it with others.

Over the last decade, IronCrypto, formerly known as OnlineCrypto, has proudly serviced thousands of customers and our aim is to make even more people's lives easier and help them keep their sensitive data secure.

I've had this password manager, seemingly forever, and have been very pleased with it. Uncomplicated design, very secure, invaluable Notes section. Highly recommend!

I've used this app for years. As long as I have my phone, or can access a computer I can get to all of my passwords.

With this update you can no longer easily see the password on a phone. Have to use a tablet of you want to see the whole password... Over all look is cluttered and ugly... UPDATE: You fixed the password issue, but there are still many problems. How come when you set the sort it doesn't save that way? It should.. For safety in unintended changes that password and other data shouldn't automatically be able to be changed just opening the account. Should require clicking on edit... * much better!!
