# Password Manager ### Direct Link ### Smart Contract ### How many supported blockchains? All OKLG-supported blockchains ### Cost of using service? $2 USD per account stored (updates are always free) ### How do I know my account information/passwords are secured? The most important thing to understand about the MTGY password manager is raw/plain account information is never stored on the blockchain. Relatively recently modern browsers have introduced some [low-level native crypto APIs](https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto) that are accessible to the web developer. We [wrote a wrapper library](https://github.com/moontography/browser-cryptography/blob/master/src/Cryptography.ts) that makes it dead simple to support encrypting plain text and decrypting ciphertext in the browser with ease. ***The only caveat is when you first use the password manager, we generate a private key that you need to ensure you back up somewhere safe***. Until your browser cache is cleared, you won't have to enter this private key again, but the moment you want to use the password manager on another machine/browser and/or your browser cache is cleared, you'll need to enter this private key again to access your information. We cannot access the information for you if you lose this key. ### How to store account info/passwords on the blockchain? 1. As stated above, when you first enter the password manager dApp, you'll need to either **Create New Encryption Key** or enter an existing one.\

2. You'll now see an empty list which you can begin creating and entering account information you'd like to store.\

3. Add a new account and you'll be able to see it after the blockchain transaction completes.
