Password Fatigue - The Burden of Too Many Passwords
About 2 min read
Password fatigue refers to the psychological burden and weariness that arise from the ever-increasing number of passwords people must manage in daily life and at work. According to a 2024 NordPass study, the average internet user manages 168 accounts, and setting and memorizing a different strong password for each one exceeds the limits of human cognitive ability. This sense of fatigue induces risky behaviors such as reusing or simplifying passwords, increasing vulnerability to attacks like credential stuffing.
The Growth in Account Numbers and Cognitive Limits
In the early 2000s, a typical user managed only a handful of online accounts. However, with the explosive spread of SaaS, the rise of subscription services, and the diversification of work tools, the number of accounts has continued to grow year after year. The number of passwords a person can comfortably remember is said to be around 3 to 5, so setting a unique, strong password for each of more than 100 accounts is impossible without supporting tools.

Risky Behaviors Caused by Password Fatigue
Password fatigue is not merely an inconvenience; it directly leads to concrete security risks. Fatigued users unconsciously adopt behaviors such as the following.
Reusing the same password across multiple services. A single breach cascades to every account.
Prioritizing memorability and setting weak passwords like "password123." They are cracked instantly by a brute-force attack.
Recording passwords on sticky notes or in spreadsheets. This creates the risk of physical shoulder surfing or file leakage.
The concrete risks of password reuse are explained in detail in the article on the dangers of password reuse.
Relief Through Password Managers
A password manager is the most practical solution to password fatigue. By memorizing just one master password, you can automatically generate and autofill a unique, random password for each service. Users are freed from the cognitive load of "remembering passwords" and can achieve both security and convenience. With a password manager, even the complex requirements demanded by a password policy become painless.
A Fundamental Solution Through Passkeys
A passkey is a technology that eliminates the need for passwords altogether and is a fundamental solution to password fatigue. Because you log in with fingerprint or facial authentication, there is no need to memorize passwords at all. Since no password exists, reuse, leakage, and phishing cannot occur in principle. As of 2025, the number of supported services is expanding rapidly, and complete liberation from password fatigue is becoming a realistic prospect.
Steps to Resolve Password Fatigue
The Relationship with Security Fatigue
Password fatigue is part of the broader concept of security fatigue. Security fatigue refers to weariness toward security measures in general, including frequent demands to change passwords, the hassle of multi-factor authentication, and the sheer number of security alerts. In its 2017 guideline revision, NIST (the U.S. National Institute of Standards and Technology) deprecated the forced periodic changing of passwords. This reflects research findings that security fatigue can actually lower security. The article on security fatigue explains countermeasures at the organizational level in detail.password security books on Amazon are also a useful reference.
Real-World Use Cases
"In an internal survey, 78% of employees reported feeling stressed about password management. After rolling out a password manager company-wide, password reset requests plummeted from 200 to 30 per month, and the load on the IT help desk was significantly reduced."
