One engineer led the rotation of more than 1,000 service credentials across 150+ applications with zero outages by building an inventory first. The method, called SCALER, runs six ordered stages: Scale, Classify, Assign, Lifecycle, Enforce, and Rotate. Accounts with no login in 90 days got disabled rather than chased down, and a temporary revert path let owners roll back a broken rotation instead of causing an outage. GitGuardian found 28.65 million new hardcoded secrets in public GitHub commits in 2025, up 34% from the year before, and when it retested secrets from 2022, more than 64% were still valid. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the safest order of steps to rotate hundreds of service account passwords without causing outages? Build an inventory before touching any password, then follow six ordered stages known as SCALER: Scale (discover accounts and where credentials spread), Classify (tie accounts to applications), Assign (named owners), Lifecycle (expiry policy), Enforce (easy rotation workflow), and Rotate (reversible change). One engineer used this to rotate over 1,000 credentials across 150+ applications with zero outages. _Teams planning a large credential rotation can study this staged approach on daily.dev before scheduling the work._ ### Why can't you use MFA to protect service account credentials? Service accounts have no human at a login screen to approve a push notification, so single sign-on, MFA, and conditional access controls, which all assume a person, don't apply. Service credentials skip the login screen entirely, meaning expired or compromised credentials go unnoticed until a job silently fails, sometimes hours later. _Engineers hardening non-human identities can dig into these gaps in people-centric controls on daily.dev._ ### What should you do if rotating a service account password breaks something downstream? Let the account owner temporarily revert to the old credential rather than leaving the break as an outage. This works on platforms that can't hold two valid passwords simultaneously; on platforms supporting two active keys, key-pair authentication lets old and new credentials overlap until validation passes, removing the need for a revert entirely. _Anyone designing a rollback strategy for credential changes can compare these approaches on daily.dev._ ## Similar posts on daily.dev - [Credential Rotation Blast Radius: 8 Questions Checklist](https://daily.dev/posts/credential-rotation-blast-radius-8-questions-checklist-psnedjz1g) · GitGuardian · 1 upvotes · 0 comments - [The password nobody owns: Taking machines to zero standing privilege \(ZSP\)](https://daily.dev/posts/the-password-nobody-owns-taking-machines-to-zero-standing-privilege-zsp--f7qft8flr) · CSO Online · 1 upvotes · 0 comments - [How GitHub used secret scanning to reach inbox zero](https://daily.dev/posts/how-github-used-secret-scanning-to-reach-inbox-zero-26vbmbpb8) · GitHub Blog · 0 upvotes · 0 comments - [GitHub ships break glass credential revocation](https://daily.dev/posts/github-ships-break-glass-credential-revocation-cii7k9djr) · Aikido Security · 0 upvotes · 0 comments - [How are DevOps teams empowered by automated secrets rotation?](https://daily.dev/posts/how-are-devops-teams-empowered-by-automated-secrets-rotation--bw7fftc4k) · Security Boulevard · 1 upvotes · 0 comments --- Tags: [#cloud](https://daily.dev/tags/cloud), [#secrets-management](https://daily.dev/tags/secrets-management), [#gitguardian](https://daily.dev/tags/gitguardian) [View this post on daily.dev](https://daily.dev/posts/rotating-1-000-service-account-passwords-with-zero-outages-zzalwc5da) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Rotating 1,000 Service Account Passwords With Zero Outages","url":"https://daily.dev/posts/rotating-1-000-service-account-passwords-with-zero-outages-zzalwc5da","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/rotating-1-000-service-account-passwords-with-zero-outages-zzalwc5da"},"datePublished":"2026-10-28T16:01:13.165Z","dateModified":"2026-10-28T16:24:53.674Z","description":"Rotating service account credentials safely requires an inventory before any password changes, not after.
