Rotating Database Credentials

Plan one credential rotation. Do not write the new password. Do not rotate during the reading.

Updated 25 October 2026 · How-To

This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.

What this hour is for

The generator drafts a plan for one account you name. prompt-for-this stands where the new secret will go. The new password does not go in the note, the ticket, or git.

Do not rotate during the reading. Do not disable authentication. Write a second account that can still get in before the only admin password moves.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep.

The change you can finish

Apply nothing while you are writing the note. When the lab window opens, it is one change on the database named in the ticket. Read the draft, then the database, then decide.

Rollback is the backup, the file, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.

  1. Name one account.
  2. Write the second account that can still connect.
  3. Leave the new secret as prompt-for-this.
  4. Do not rotate.
  5. Stop.

Mistakes that outlive the statement

Rotating Database Credentials goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.

Decisions to write down

One decision for Rotating Database Credentials: One account is written. A second account is written. The new secret is not in the note. And nothing was rotated.

Checks before you call it done

Confirm this before you call the change done: The account is written. The second account is written. prompt-for-this is still the secret. Nothing was rotated. And the database is yours. If one of those fails, stop.

# One account. prompt-for-this is not a password.
# Do not write the new secret in the note.
# Do not rotate during the reading.
# Do not disable authentication.

Before you leave the database

Rotating Database Credentials ends when the database in the prompt is the database in the ticket. If it is not, you are on the wrong database. Stop.

The draft stays a draft until a person has read the names in it. A generator does not log into the database. You delete a line that names a host, a database, or an account you did not write down.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a database because a draft included them.

prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. A sample password in a draft is replaced. It is not a password you keep.

One change is the window. If two things move and the result is wrong, you will not know which one did it.

If the same step fails twice, stop for the day. Restore the copy you took first.

A second person reads the database name and the change aloud. If they cannot find them in the ticket, the note is not done.

This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a database you do not administer. You do not disable authentication, a firewall, or TLS to make a check pass.
