Hi, could some one explain how are seedphrases considered to be super secure? If it’s just a random string of words from a well-known list of words, what stops someone with a simple python script generating random phrases and trying to open wallets with them?

The entropy of pass phrases is higher than that of most passwords that are used in real life.

Of course if you have a password manager you are better off having a long random string.

What is keeping people from brute forcing is that the hashing algorithms used are purposefully slow, so they limit how many combinations you can check per second.
