Credit Freeze vs. Credit Lock: What's the Difference?
Both a freeze and a lock restrict access to your credit report, but they work differently and offer different protections.
Credit freeze
A credit freeze is a right guaranteed by federal law, is always free, and offers strong legal protections around how it can be lifted. It typically requires a PIN or password to unlock.
Credit lock
A credit lock is a convenience feature offered by the bureaus themselves (often bundled with paid monitoring products), toggled instantly through an app, but without the same statutory guarantees as a freeze.
Which offers stronger protection
A freeze is generally considered the stronger, more legally protected option, though a lock can be more convenient for people who frequently apply for credit.
Which to choose after a breach
For serious breach exposure — especially involving a Social Security number — a free credit freeze at all three bureaus is usually the recommended first move.
Key takeaway
A freeze is free and legally guaranteed; a lock is a convenience feature. After a serious breach, a freeze is usually the stronger choice.
