The compromised data included email addresses and passwords stored as salted SHA-1 hashes—not passwords reported as readable plaintext. If you reused that password, change it anywhere else you used it, starting with your email and other sensitive accounts.
What happened in the Tumblr breach?
HIBP’s breach entry dates the incident to February 2013 and lists 65.5 million affected addresses. That is HIBP’s count of addresses, not a verified count of distinct people. HIBP also says the data was later offered for sale on a dark-market website and that it added the breach to its records on May 29, 2016. These details come from HIBP, not an original Tumblr incident notice: Have I Been Pwned’s Tumblr breach entry.
The available record does not establish how attackers obtained the data, when Tumblr discovered the breach, or the company’s complete response at the time. Those details should not be treated as known.
What information was exposed? Were passwords leaked in plaintext?
HIBP lists email addresses and passwords stored as salted SHA-1 hashes. A hash is not the same as a readable plaintext password, but that distinction does not make an old or reused password safe. If you used the same password on another service, change it there too.

Was your account affected?
If you used Tumblr in or before 2013, you can check an email address with HIBP’s Tumblr breach record and its account-checking service. A result can indicate that an address appears in the recorded breach data; it does not prove who used the account or whether anyone accessed it afterward.
What should you do if you reused your Tumblr password?
- Replace the reused password. Change it on every account where you used it. Prioritize the email account tied to those services, then financial and other sensitive accounts. HIBP specifically advises changing the affected password wherever it was reused.
- Make each replacement unique. Tumblr recommends a password manager to generate and store strong, unique passwords. Its Protecting Your Account guidance also describes passphrases as an alternative for people who prefer a memorable password.
- Turn on two-factor authentication. Where available, use an authenticator app as an additional login factor. Tumblr advises users to generate and save backup codes when enabling two-factor authentication; keep those codes somewhere secure and separate from the account.
- Secure the email account. Because account resets often depend on email access, use a unique password for that inbox and enable two-factor authentication there if available.
What if your Tumblr account seems hacked or you are locked out?
If you can still sign in
Change your Tumblr password, enable two-factor authentication, and review connected applications. Revoke access for apps you do not recognize or trust. If you entered your credentials on a fake login page, change that password anywhere it was used and enable two-factor authentication. Tumblr’s Compromised or Hacked Accounts guidance covers these steps.

If you cannot sign in
If you can access the email address registered to the Tumblr account, use Tumblr’s password-reset page. For an account protected by two-factor authentication, a saved backup code can be used in place of an authenticator code; each backup code works once. If you do not have a backup code, or reset or authentication codes are not arriving, contact Tumblr through Account Access support. Tumblr says it cannot recover an account if you cannot access its registered email address. See its Tumblr Account Recovery and Trouble Logging In guidance.

- Do not send your password to anyone claiming to be Tumblr support. Tumblr says staff will never ask for it.
- Use Tumblr’s official Help Center and account-recovery routes rather than links in unsolicited messages.
- Do not reuse a replacement password on other accounts; a password change only helps if the new credential is unique.
