How Hard Is It to Guess a Seed Phrase?


What’s a Seed Phrase?

A seed phrase, also called a backup or recovery phrase, is a word sequence that is used to restore or regain access to a cryptocurrency wallet. Such phrases are generally between 12 and 24 words long and are created by a cryptographically safe generator of random numbers. Here, we’ll look more closely at seed phrases, why they’re essential, and how to use them correctly, and then discuss how hard it is to guess a seed phrase.

Why Is the Seed Phrase Significant?

  • A seed phrase is required to access your cryptocurrency wallet. Without it, you wouldn’t be able to access your funds.

  • Seed phrases serve as a backup, allowing you to regain access to the cryptocurrency even if you forget your passwords.

  • Seed phrases are additionally used to access your wallet on a new device or to restore cryptocurrency assets if you lose your smartphone or have it stolen.

Seed phrases are an important part of safeguarding your cryptocurrency wallet to make sure it remains secure after you buy, sell, convert, swap, stake, or perform any other transactions with your cryptocurrency. It is critical to generate and store the seed phrase safely.

  • While seed phrases are essential, simply creating and storing them is insufficient. It’s also crucial to check your seed phrase regularly to make sure that it remains safe and secure. Remember that the safety of your seed phrase can only be as good as the safety of the place it’s kept.

A further major consideration is to avoid using the same seed phrase for several cryptocurrency wallets or accounts. In case one wallet or account is hacked, each must have its own seed phrase. This will keep the other wallets or accounts secure as well.

Can Someone Guess My Seed Phrase?

To answer the question, “how hard is it to guess a seed phrase?” we need to look at some basic propositions of probability theory. The longer the encryption and the more characters it contains, the lower the risk of hacking. The complexity of a phrase is determined by its length as well as the technology used to obtain it. A seed phrase consisting of 12 words created by a random word generator would be almost impossible to guess, given that there are more than 132 quadrillion potential word combinations.

They’re nearly as strong as cryptocurrency private keys, so your chances of guessing a seed phrase are comparable to those of guessing the private key of a cryptocurrency wallet. In this scenario, however, the seed phrase is smaller and less sophisticated. If the technique applied to generate it isn’t genuinely random, the seed phrase is regarded as easier to predict. To guarantee the security of your cryptocurrency assets, it is critical to have a long and complicated seed phrase created using a secure technique.

Although guessing seed phrases is almost impossible, it is still critical to be careful of seed phrase fraud, which is becoming more prevalent. Somebody might try to deceive you into providing them with the seed phrase. Scammers may apply social engineering techniques such as impersonating a client service employee from a reputable wallet provider or by providing a “recovery service” for missing seed phrases. Don’t ever provide your seed phrase to anybody, even if they appear to come from a trustworthy firm.

How to Safeguard a Seed Phrase

  • Create your seed phrase with trusted wallet software;

  • Use a piece of paper and a pen to write down the phrase and save it somewhere secure. It is critical to keep the phrase private and secure, as anybody who has access to it can access your money;

  • Make reserve copies of the phrase and keep them in separate locations in case one is lost or destroyed;

  • Do not save the seed phrase to a computer or smartphone since it might be hacked;

  • Avoid taking a picture or snapshot of the seed phrase because these can be stolen easily;

  • Store your seed in a secure location, for example, in a safe deposit box or a secure area of your house;

  • Do not reveal your seed phrase to anybody, including family members or friends, and do not save it in a cloud storage service, which may be hacked and accessed;

  • Apply encryption to the seed phrase by using a password manager, such as LastPass or 1Password.

Another factor to consider when using seed words is the risk of human error. Even if you take all the required precautions to safeguard the seed phrase, there is still the possibility that you may misplace it or forget where you placed it. This is why it’s critical to have a backup strategy in case your seed word is lost or stolen.

  1. You may use a service to protect the seed phrase securely. To keep a phrase secure, these services often employ cutting-edge security features such as encryption and multi-factor authentication. Choose only reliable and trustworthy seed phrase-storing providers.

  2. A hardware wallet is another possibility. These are physical devices that store your seed phrase offline on a secure chip. They are considered one of the most secure ways of storing the seed phrase. For example, some wallets employ BIP39 seed phrases, which adhere to a certain standard. Other wallets may use a different type of phrase. It is vital to understand the distinctions between several seed phrases and to choose the one advised by your wallet provider.


Seed phrases are a critical component of safeguarding your cryptocurrency assets. You may secure your seed phrase and your funds by adhering to the best procedures for creating and storing them. Furthermore, having a backup plan on hand is a great way to go. 

Using a hardware wallet and understanding the types of seed phrases available can add an extra layer of protection. It’s crucial to note that the seed phrase “safety” is only as strong as the security measures you implement, so take the appropriate precautions to safeguard your assets and have peace of mind knowing that your funds are secure.
