Knowledge

Password Security Basics

What is entropy?
Entropy measures password randomness. Larger character sets and longer lengths increase entropy and make guessing harder.
Length and character sets
Length has the biggest impact on security. Adding symbols increases combinations and strengthens passwords.
Handling similar symbols
Characters like O/0 and l/1 can cause typing errors. Exclude them when manual entry matters.
Safe storage tips
Store passwords in a trusted manager and avoid reusing the same password across services.

FAQ

Password Generator FAQ

How is the strength calculated?
It estimates entropy based on the selected character set size and length.
Do I need to include symbols?
Not required, but longer lengths or symbols improve security.
When should I exclude similar characters?
When people need to type the password or PIN manually to reduce mistakes.
Are passwords stored anywhere?
No. Everything is generated locally and never sent to a server.
How does the length range work?
Each password picks a random length within your range.
Will I get the same password again?
No, each run uses cryptographically secure randomness.
Does generating many reduce security?
No, each password is generated independently.
