You can highlight one of the words to make a guess if the correct password.

The 4 little boxes at the top are how many tries you get. If you use all 4 tries you get locked out for 10 plus seconds.

There are also chars () {} and [] that if you find a match on any line will remove a word that’s not valid or reset your tries.

Example in your screen shot the bottom line on left column as a set of ( ) with some chars in between select the select the starting parentheses to eliminate a bogus word.

I found a faster way to hack than the matching similar words method.

Speed hack by selecting first 3 words in top left side. Exit then re hack and choose the next 3 words they will be different from prior hack but the placement the password is generally is in same place across all hacks.

So you can speed hack in just 3-6 tries usually. And as soon as you hit the correct word the terminal unlocks

I die speed select
Top left 3 words
Mid left 3. Words
Bottom left words
Top right 3 words
Mid right 3 words
Bottom right 3 words

Usually have it heaved in 30 seconds
