I am trying to understand how exactly MetaMask is generating the initial entropy to create its mnemonic key. There are questions like this, MetaMask's documentation, or their GitHub but I can't find the answer I'm looking for in either one.

What is the source of entropy in MetaMask for generating mnemonic words (if they are using BIP39)? If not BIP39, what standard are they using to create mnemonic words?

Read this article. She covers in sufficient detail the work on creating mnemonic phrases and not only. https://medium.com/mycrypto/the-journey-from-mnemonic-phrase-to-address-6c5e86e11e14
