Accounts are stored on the blockchain, and these private keys unlock those accounts.

Your SRP is used locally to derive private keys, one per account/address.

If someone does ask for it, they are likely trying to scam you or steal your funds. MetaMask representatives will never ask for your Secret Recovery Phrase, even in a customer support scenario. MetaMask does not keep your SRP: you are the custodian of your wallet. If someone has this secret, they have complete access to the wallet.

The Secret Recovery Phrase is the secret that controls the wallet.

There are a number of important features to note here: In other words, your Secret Recovery Phrase will always generate the same set of accounts derived from it. In computer science, deterministic is used to describe a process (usually an algorithm of some kind) that will always generate the same result. That number is then used to deterministically generate your accounts, and you may hear people refer to deterministic wallets.

Some older seeds generated by the Brave browser, and some hardware wallets, use 24-word phrases.Įach one of these words corresponds to a series of numbers, and when placed in a specific order, represent a much more user-friendly way to remember a very, very long number. In MetaMask and many other Ethereum-compatible technologies, there are 12 words in a seed phrase. In simple terms, a series of words are selected with a high level of randomness from a specific list of words. Now, if you want a technical explanation: Seed phrases as we know them today were codified for usage in Bitcoin, according to a standard referred to as Bitcoin Improvement Proposal 39, or BIP-39. You can think of the SRP like a keyring, and it holds as many private keys as you could want: and each one of those keys controls an account. All of your accounts are mathematically derived from your Secret Recovery Phrase.

One of the key (you'll see what I did there) technologies underlying MetaMask, and most user account-related tools in the crypto space is the seed phrase, or as it's referred to in MetaMask, your Secret Recovery Phrase. We'll walk you through these secrets one at a time. MetaMask has three different types of secret that are used in different ways to keep your wallet, and your accounts, private and safe: The Secret Recovery Phrase, the password, and private keys. We're used to the app keeping our data, presumably on some sort of computer that belongs to the company. Most of us are used to creating an account with an app, or service and being able to, for example, write to support to reset our password or username. Public blockchain technology uses a very different set of tools to secure user data, compared to traditional online technologies. MetaMask: a different model of account security How MetaMask's security differs from traditional web accounts.It's completely free, available in multiple languages, and includes useful tools such as simulations to help you find your feet with MetaMask. USB device access is also needed to export data to CSV file format.Head to MetaMask Learn for a straightforward learning experience designed specifically for newcomers to web3.

The only permission this app has (until Android 5) is to access the USB device to backup/restore the data file in case you lose your phone. Not applies to the Cloud version and iOS version : Unlike other similar Android apps, aWallet has no internet access permission (forever). Supports auto-destruction of the data file after a predefined number of unsuccessful unlocks have been tried. Repetitive hashing makes a brute force attack more difficult. The result is hashed 1000 times by SHA-256. The key to open the data file is created by combining your master password with the 512-bit 'salt'.

Salt helps to protect from off-line dictionary attacks. Uses a randomly generated 'salt' combined with the Master password. The app itself does not store any hint to the actual cipher, key size, or cipher mode of operation. This was inspired by TrueCryp t and makes brute force attacks longer. When the data file is decrypted, up to all combinations of algorithm, key size, and cipher mode of operation (CBC, CFB, OFB and ECB) are tried with the Master password to unlock the data file. Even the choice of Favorite Category is encrypted.Įncrypts data using AES and Blowfish algorithms with key sizes of 256, 192 and 128 bits. All data is encrypted, including Entry names, Category definitions, and the data itself.
