All lowercase: 26 possible characters
Possibilities in an 8 character password: 26^8 = 208,827,064,576
Dictionary attacks are extemely trivial
Brute force attacks are probably trivial
English letter pairing frequency drastically lowers the effective search space
Upper + lower + number: 62 possible characters
Possibilities in an 8 character password: 62^8 = an answer in scientific notation because the number is fuckhuge
Dictionary attacks are no longer trivial
Brute force attacks are non-trivial
English letter pairing frequency drastically lowers the effective search space, but is blunted by numbers and caps
Password entropy checks could be performed in order to do away with character classes, but then communicating the nature of a rejected password means telling the user "make the password more better" without an explicit reason their password was rejected.
