How to Create a Strong Password in 2026
Most people know their passwords are weak. The problem is that the old advice – mix uppercase, lowercase, numbers, and symbols – produces passwords that are hard for humans to remember and easy for computers to crack.
Here is what actually works.
Length beats complexity
A 20-character passphrase made of common words is stronger than an 8-character string of random symbols. The math is simple: every additional character multiplies the number of possible combinations.
NIST Password Guidelines: What Changed and Why It Matters
The National Institute of Standards and Technology (NIST) sets the password policies that US federal agencies must follow. Their guidelines (SP 800-63B) have rippled out to influence corporate policies worldwide.
The most recent revision threw out decades of conventional wisdom.
What NIST dropped
Mandatory complexity rules. The old requirement to mix uppercase, lowercase,
numbers, and special characters is gone. NIST found that these rules lead to
predictable patterns (Password1!, Summer2026$) that are easy to guess.
