How often should you change passwords?
Passwords should not be constantly changed without reason. The decisive factor is the change after specific risks, leaks or if there is weak legacy.
Why blanket rotation is problematic
When users have to change passwords according to rigid deadlines, often only weak variations of the same basic pattern emerge. This increases the effort, but not necessarily security.
It makes more sense to change if there is a real reason for it.
When a password change is really necessary
- After a data leak or suspected compromise.
- If the password has been reused or is too weak.
- When an account has become particularly important and the old quality is no longer sufficient.
What modern password maintenance looks like
Instead of constant rotation, strong, unique passwords plus MFA and leak monitoring are usually more effective. This keeps the focus on real risks instead of calendar rules.
For companies, this means: processes should prioritize incidents, not force ritual changes.
Quick checklist
The most important actions from this guide in compact form.
- Change passwords immediately after leaks, warnings or reuse.
- Regularly check critical accounts for quality, do not rotate them blindly.
- It's better to keep a strong, unique password than to constantly vary a weak pattern.
