Does it really improve a password if at least one character of each group (a-z,A-Z,0-9) is included? [duplicate]
Many password policies required at least one character of each group (upper case, lower case, symbols, and numbers) in the password.
Does this really improve a passwords strength?
e.g.: Is (number included)
3i{M?tofQPI.'C`dfmSK
really stronger than (no number)
ni{M?tofQPI.'C`dfmSK
Please try to keep answers simple. As the question may indicate, I'm not really skilled in cryptographic science.
