The numbers
What the record shows
What leaked
5 kinds of data were exposed
The universal account key. Exposed addresses get targeted with credential-stuffing and phishing that name the breached site to look legitimate.
Rough location and ISP. Low direct harm, useful for correlating accounts.
Real names turn generic spam into convincing, personally addressed phishing.
Not enough to charge on its own, but enough to make a fraudster on the phone sound like your bank.
The one that matters most. Even hashed passwords get cracked at scale, and every account where this password was reused is now reachable.
In this order
What to do now
Reset the Roll20 password first
Use the official forgot-password flow on roll20.net directly, never a link from an email about the breach; breach news is prime phishing bait.
Kill the reuse, which is the real damage
Every account sharing the exposed password is now one automated attempt from gone. This is the tedious part, and it is the part Repass automates: it finds the accounts and runs each site's official reset flow for you.
Scan your email for the rest of your exposure
Run the free breach scan on the address you use most. Roll20 is one breach; the median active email address appears in several, and what to fix first depends on the full picture.
Turn on two-factor authentication
A leaked password with a second factor in front of it is a locked door with a stolen key that no longer fits. Prefer an authenticator app over texted codes where the service offers the choice.
Questions
Roll20 breach FAQ
Was my Roll20 account affected by the breach?
The record covers 3,994,436 accounts. The quick way to check is a breach scan against your own email address, which searches this breach and hundreds of others at once. Repass runs one free on its homepage.
What should I change first after the Roll20 breach?
The Roll20 password itself, immediately. Then every other account where you used the same or a similar password, because that reuse is what attackers actually exploit.
Is changing my Roll20 password enough?
Only if that password lived nowhere else. Credential-stuffing takes leaked email-and-password pairs and tries them on banks, mailboxes and stores at machine speed, so the reused copies matter more than the original. A reused password is a breach of every account that shares it.
Were payment cards exposed in the Roll20 breach?
The record lists partial credit card data among the exposed data. Watch the statements on any card used there, and treat calls or emails that quote card details as hostile until proven otherwise; quoting real fragments is how fraudsters borrow your bank's credibility.
Where does this breach data come from?
From the public index maintained by Have I Been Pwned, which verifies breaches before listing them. This page renders the structured record: dates, account count and exposed data classes.
How do I find out what else has leaked about me?
Run a breach scan on your email address. It returns every verified breach that lists the address, which is the honest starting point for deciding what to reset first. Repass then resets the passwords for you, one official flow at a time, and seals each new one in an encrypted vault.
