TL;DR: A credit freeze is a legal right under US federal law, free for everyone, and restricts access to your credit report so new creditors generally can't view it — it's managed directly with each of the three credit bureaus.
How to Set Up a Credit Lock vs a Credit Freeze — a clear, step-by-step guide to what to do and how long it takes.
Step 1: Understand a credit freeze
A credit freeze is a legal right under US federal law, free for everyone, and restricts access to your credit report so new creditors generally can't view it — it's managed directly with each of the three credit bureaus.
Step 2: Understand a credit lock
A credit lock is a similar but separate product, usually offered through a bureau's own app or paid credit monitoring service, that can often be toggled on and off instantly — but it isn't governed by the same federal freeze protections.
Step 3: Compare the practical differences
Freezes are free and backed by federal law with clear consumer protections; locks are typically faster to toggle via an app but may come bundled with a paid subscription and rely on the provider's own terms rather than statute.
Step 4: Decide which fits your situation
If you want the strongest, most broadly recognized protection with no cost, a freeze is generally the better default; a lock can be convenient if you frequently need to open and close access and don't mind using a bureau's app.
Step 5: Either way, cover all three bureaus
Whichever you choose, you need to apply it separately at Equifax, Experian, and TransUnion, since a freeze or lock at one bureau does not extend to the others.
