how to rotate passwords on many accounts at once

TL;DR

Rotate fleet passwords in small batches, one site at a time, verifying each new login before moving on. Stagger the batches across hours or days so the pattern does not look like a credential-stuffing attack. Update the vault entry immediately after each successful rotation, and log what changed.

how to rotate passwords on many accounts at once

Use this when

• Doing scheduled credential rotation across agent accounts
• Responding to a suspected exposure
• Onboarding accounts into a new vault

Not for this skill when

• Only one or two accounts need it (just do them by hand)
• You do not control the accounts
• The site offers API keys or tokens (rotate those instead of passwords)

Steps

1. Build the inventory. List every account, its venue, and the last rotation date. Sort by risk: exposed or shared credentials first. Expected: a complete list, no mystery accounts.

rotation queue:
  1. [venue] / [account] - last rotated 2026-07-01
  2. [venue] / [account] - last rotated 2026-08-15

1. Work one site at a time. Open the site's password-change flow, set the new password, and log back in to verify before touching the next account. Expected: every rotation is verified working.

1. Update the vault entry immediately. The new credential goes into the vault before you close the tab, never into a scratch note. Expected: the vault always holds the current password.

1. Stagger batches. Do a handful of accounts, pause for an hour or more, then continue. Ten password changes in ten minutes from one IP invites fraud detection. Expected: no account gets locked for suspicious activity.

1. Log the rotation per account with the date. Expected: next quarter you know exactly what is due.

Variant phrasings

bulk password change for bot accounts

Batch by site, verify each login, update the vault, and stagger so it does not trip fraud detection.

rotating credentials across a fleet

Inventory, risk order, one site at a time, vault update per rotation, logged dates.

password rotation without getting locked out

Slow down. A few accounts per hour with verified logins beats a fast batch that triggers a lockout.

Why it happens

Password-change flows are guarded by the same abuse detection as logins. A burst of changes from one IP with automated timing looks exactly like an account-takeover wave, so sites throttle or lock it. Going slow is not just polite, it is the only way the rotations actually complete.

Edge cases / pitfalls

• Some sites force-logout all sessions on password change; re-authenticate your workers after.
• Sites with mandatory 2FA need the second factor in the rotation flow; plan for it.
• If a rotation fails midway, the vault must reflect which password is actually live.
• Never reuse one new password across accounts; generate a unique one per account.
