Direct Answer
To unfreeze your credit, log into each bureau's website and use the PIN or account credentials you set when you froze it. You can unfreeze permanently or for a temporary window (1 day, 1 week, etc.). Each bureau is separate — you must unfreeze at all three if a lender needs to pull all three. Here at Credisure Fix, we coach you on freeze/thaw timing so it never delays a real loan application.
