How does a seed phrase work? When you create a crypto wallet, a seed phrase is automatically generated. The seed phrase is a representation of a long string of random numbers — and your wallet uses it to generate the private keys that let you send and spend your crypto.
How do keys work in bitcoin?
When you first buy cryptocurrency, you are issued two keys: a public key, which works like an email address (meaning you can safely share it with others, allowing you to send or receive funds), and a private key, which is typically a string of letters and numbers (and which is not to be shared with anyone).

How does a 12 word phrase work?
A simple explanation of how secret phrases work is that the wallet has a list of words taken from a dictionary, with each word assigned to a number. The secret phrase can be converted to a number which is used as the seed integer to a deterministic wallet that generates all the key pairs used in the wallet.
How secure is a 12 word seed phrase?
The total number seed phrases are 1,329,227,995,784,920,000,000,000,000,000,000,000 – if I right counted – 12 words. This is equivalent to 2132, meaning 132 bits of security. Some of these bits are not valid – equating to certain invalid 12-word combinations – so the security is actually 2128, which is 128 bits.

How many bitcoin seeds are there?
If the phrase contains only 12 random words, the number of possible combinations would be 2048^12 = 2^132. That’s about as secure as Bitcoin private keys themselves, so your chance of getting the seed is about as good as guessing the private key of a Bitcoin address.
