Password Success Rate
Password success rate is an operational measure of how often login attempts result in successful authentication. Organizations commonly calculate it by dividing successful authentication events by total login attempts and multiplying the result by 100 to get the successful login percentage. Related measures include first-attempt password success, recovery rate, and an organization-defined login-to-authentication ratio that compares application login activity with authentication events recorded by an identity provider. Because organizations define login attempts differently, IT teams should establish a consistent measurement period and account for factors such as repeated retries, lockouts, password resets, multifactor authentication (MFA), and single sign-on (SSO) logins. A low password success rate may indicate forgotten credentials, password problems, account recovery delays, or a system bounce-back that returns users to a login screen without clearly explaining what went wrong.
At the enterprise level, password success rate helps IT and help desk teams understand how traditional password challenges affect security and operations. Common causes of unsuccessful authentication include password fatigue, reused or expired passwords, unclear password policies, unavailable recovery methods, inconsistent application requirements, and difficulty accessing systems from shared devices. These issues can create a drain on the IT helpdesk due to a high volume of password-related requests. They can also interrupt critical tasks for frontline workers, delay onboarding when new employees cannot access required systems, and encourage insecure workarounds such as writing down passwords or sharing credentials. Tracking password success rate alongside login volume, lockout frequency, account recovery time, password reset requests, and time spent resolving password problems gives organizations a more complete view of password effectiveness and password security.
While it is still relevant to ask, “How do I know if a password is strong enough?”, complexity alone does not solve enterprise credential challenges. Password strength tests can estimate whether a password is difficult to guess, and organizations can use policies that block common, expected, or compromised passwords. However, password strength test results should not be treated as a guarantee of password security, and users should never enter a password they actually use into an untrusted online testing tool. Current guidance from the National Institute of Standards and Technology (NIST) emphasizes effective length, screening against compromised passwords, and rate limiting rather than arbitrary composition rules or frequent mandatory changes. For IT teams determining how to manage passwords for a company, business password managers, encrypted credential vaults, and centralized credential management can help generate, store, and control access to passwords. Depending on the system and use case, password management tools may also support password rotation, credential checkout, expiration, and audit trails while reducing exposure from reuse and informal sharing.
What is an alternative to passwords?
When repeated failed logins, lockouts, forgotten passwords, and slow recovery consume time and create risk, organizations may want to consider password alternatives. Passwordless authentication can reduce reliance on memorized application passwords. Depending on the implementation, passwordless methods may include badge tap, biometrics, passkeys, device-bound credentials, security keys, or other phishing-resistant authenticators. SSO reduces the number of passwords users must remember, while MFA adds a protective layer to traditional login methods by requiring additional verification.
Risk signals such as an impossible-location event, when the same account appears to be used from geographically distant locations within an implausibly short period, may prompt additional verification or other risk-based controls. To evaluate return on investment, organizations can compare the costs of password-related help desk calls, recovery time, lockout resolution, lost productivity, and security incidents with the costs of deploying and maintaining credential managers, vaults, SSO, MFA, and passwordless solutions. These measures help to mitigate authentication risks while also reducing friction, supporting immediate productivity, improving onboarding, and freeing IT and cybersecurity resources for higher-priority work.
Imprivata Enterprise Access Management (EAM) helps organizations apply these principles across shared workstations, virtual desktops, applications, and other critical workflows. EAM supports SSO for modern and legacy applications, MFA, passwordless authentication, badge access, fast user switching, and analytics that help organizations monitor access behavior and improve controls. By reducing reliance on passwords while supporting access to modern and legacy applications, Imprivata can help organizations address password fatigue, reduce password-related help desk calls, and give clinicians and other frontline workers faster, frictionless access to the systems they need.
