ToolWrenMost password advice is outdated. The single biggest factor in how hard a password is to crack is its length, not whether it has a ! in it. Here is what actually works.
Length beats complexity
Each extra character multiplies the number of possible combinations, so a long password is exponentially harder to brute-force than a short 'complex' one.

Passphrases: long and memorable
A passphrase strings together several random words. It is long (so very strong) yet far easier to remember and type than random symbols. Create one with our passphrase generator.
The three rules that matter
1. Make them long. 2. Make every account unique — so one breach does not unlock everything. 3. Use a password manager so you do not have to remember dozens of them. Turn on two-factor authentication wherever possible.
How passwords are stored
Reputable services never store your actual password. They store a one-way hash of it, so even if their database leaks, your password is not directly exposed (assuming a strong, salted hashing algorithm). You can experiment with hashing on our hash generator. For random unique identifiers in software, see the UUID generator.
