Your password for this forum could be even a bit smaller, BUT i don't even know if you are using Uppercase or Numbers or Special, if you are using "real" words or as this case you are using random all togheter
A "secret phrase" is made by Words, and I (we) know the words, and I (we) know there are NO numbers, NO special characters, NO uppercase...
So, I very deliberately chose a password with 20 random characters drawn from uppercase, lowercase, numbers, and symbols, for my example.
There are 95 printable ASCII characters. 20 such characters gives 20
95 combinations, which is 3.58*10
39. This is the smallest number of characters needed to produce a password at least as strong as a 12 word seed phrase, which has 2
128 combinations, which is 3.40*10
38.
So even if you don't know if my password is using real words, or dates, or patterns, or numbers, or symbols, or upper or lower case, or whatever, and you have to brute force every possible combination, that password is still roughly as secure as a 12 word seed phrase, even when you know the full word list.
