BIP39 Tool: A Bitcoin Mnemonic Generator Explained

I believe, by now you must have read my previous article on Bitcoin seed & Mnemonic phrase, if you haven’t read it, please do so because after that you will be able to appreciate the concept of BIP39 and Bitcoin mnemonic generator thoroughly.

But anyways, let me get started with BIP39:

BIP 39 is another Bitcoin Improvement Protocol like BIP 38, and it is used to generate Bitcoin mnemonics (i.e., 12-word seeds) that are human readable. These mnemonics are also called BIP39 mnemonics.

So, What Is A BIP 39 tool or Bitcoin Mnemonic Generator?

A tool that is used to generate BIP39 mnemonic phrases randomly is called a Bitcoin mnemonic generator or BIP 39 tool.

But many a time, this tool is also used to covert BIP39 mnemonic phrases to public addresses and private keys.

BIP39 describes the implementation of a mnemonic sentence.

It consists of two parts: generating the mnemonic and converting it into a binary seed. The English-language wordlist for the BIP39 standard has 2048 words, so if the phrase contained only 12 random words, the number of possible combinations would be 2048¹² = 2¹³², and the phrase would have 132 security bits.

However, some of the data in a BIP39 phrase is not random, so the actual security of a 12-word BIP39 mnemonic phrase is only 128 bits. This is approximately the same strength as all Bitcoin private keys, so most experts consider it to be sufficiently secure.

Note: It is not advisable to invent your own mnemonic phrase because humans are bad at generating randomness. That’s why the best way is to allow the wallet software or a Bitcoin mnemonic generator to generate the phrase which you can write down. Also, remember to safely store this phrase because losing this would mean losing all your funds. (Wikipedia)

How To Use a BIP39 Tool or Bitcoin Mnemonic Generator?

Using a mnemonic generator is easy, and for this tutorial, we are taking the example of Bitcoin because it is the most popular currency in the market and many people relate with it.

Iancoleman tool is the most reliable bip39 passphrase generator which is used for this purpose, and it is also popular in the market as a BIP39 tool. Here is the step by step procedure to generate Bitcoin mnemonic using it:

#1. Go to iancoleman.io and select the length of your mnemonic. You can also vary the length of your random mnemonic by using the option shown below.

 

#2. Once you have decided the length, you can select your mnemonic language as ‘English.’ You may choose other languages based on your choice.

Note: Make sure you have selected ‘Bitcoin’ in the Coin section, and your BIP 39 Mnemonic will be ready that you can copy paste on a piece of paper to secure it safely.

This tool is also known by the other two names such as:

  • bitcoin passphrase generator
  • bitcoin seed generator

That’s because this Bitcoin mnemonic generator can eventually calculate the other two things that I have mentioned above.

 

You can find the seed and private keys below on the same page of the tool if you scroll down.

And if you have read, my previous article on HD wallets, you will be able to recollect and understand the process of the deterministic-key generation which is ultimately derived from BIP39 mnemonic only.

Conclusion

All the modern Bitcoin wallets have BIP39 tool inbuilt in them which is ultimately responsible for providing you the Bitcoin mnemonics of varying lengths.

Usually, you are not advised to use this online tool, and there is no need also when modern-day wallets are doing all these things for you.

But this BIP39 tool might be required in cases of Bitcoin forks where you are required to get specific private keys related to a particular public address.

In such cases, you can take this tool offline and use it to determine the private keys that you need and later can import it in other wallets to claim Bitcoin forks.

So that’s all from our side in this guide on Bitcoin mnemonic generator and if you liked this article? Then do share it with your friends and family members on Twitter !!
