Security profiles explained
The High Security profile (20 chars, all types) is ideal for most online accounts — email, banking, shopping. Maximum Security (32 chars) is for master passwords, encryption keys, and VPN credentials. Memorable excludes ambiguous characters like 0/O and l/1/I to reduce transcription errors when typing manually.
What is entropy and why does it matter?
Entropy measures password unpredictability in bits. Each additional bit doubles the time required to brute-force. At 60 bits, a dedicated GPU cracker would take thousands of years. At 128 bits, it exceeds the estimated compute capacity of all computers ever built. For critical accounts, target 80+ bits.
How to use bulk passwords safely
- Generate 5–20 passwords and pick one — or use all of them for multiple accounts.
- Copy all passwords to a password manager immediately — never save to a text file.
- Never screenshot or photograph passwords.
- Trusted password managers: Bitwarden (open source), 1Password, KeePass, Dashlane.
