What is a Secret Recovery Phrase and how to back it up
The use of a seed phrase, or Secret Recovery Phrase, is a standard most crypto-wallets use. It's generated randomly when you create a MetaMask account, which is unique, and serves to generate addresses.
When you create a MetaMask wallet, you are given your 12-word Secret Recovery Phrase. MetaMask does not control any of your personal or private data on our servers. Everything is encrypted in your browser and protected via your MetaMask password. So, when you lose your MetaMask accounts, and need to restore MetaMask, you can only do that with your Secret Recovery Phrase.
Why you need to store your Secret Recovery Phrase
MetaMask is not a cloud-based solution. If your device breaks, is lost, stolen, or has data corruption, there is no way for the MetaMask Support team to recover this for you. This Secret Recovery Phrase is the only way to recover your MetaMask accounts.
Don’t share your Secret Recovery Phrase and private keys
Anyone who has your Secret Recovery Phrase or private keys could send Ether or tokens from your accounts. Never share them with anyone, including the MetaMask team. We will never ask for you to provide this. If someone claims that we do, insist on not sharing. Please report to us the person who claims to be MetaMask team member, and asks for your Secret Recovery Phrase and/or private keys via firstname.lastname@example.org.
If you have large amount of ETH or tokens in your accounts, consider getting a hardware wallet.
Hardware wallets are commonly thought to be the safest, and most robust device to store your Ethers or tokens. It signs transactions through the private keys which are stored offline.
There is no such thing as too much safety. The basic guide here is by no means comprehensive. Always learn how to better protect your tokens, by learning from the community, informative materials or discussion channels.
