When getting started with Bitcoin or any other cryptocurrency, there are two terms you will hear a lot which are- private key and seed phrase. They might sound similar, but they play different roles in keeping your funds safe....
1) Private Keys
When you create a crypto wallet, it generates two things- a public key (like your account number, which you can share to receive funds) and a private key (your secret code, which must always remain hidden). The private key makes use of an alphanumeric string and it proves that you are the true owner of the coins in that wallet. Anyone who has access to it can be in full control of your funds, send them, spend them, or even transfer them to their own account.

2) Seed Phrase
A seed phrase (also called a recovery phrase) is a group of 12 or 24 random words that can recreate all the private keys in your wallet. This means if your phone gets lost or spoils, you can still recover your wallet, so as far as you have your seed phrase with you. Just think of seed phrase as the master key to all your wallet.

Why They Matter
Your pivate key and seed phrase are the two central backbone of your crypto security this is because if anyone gets hold on either of them they can take all your funds. That’s why you should:

- Never share them with anyone.

- Store them offline (write them on paper or make use of a hardware backup).

-Avoid saving them in your phone or computer where they could be hacked.
