Marriott Bonvoy account hacked? Here’s what to do
Move fast and in the right order: reclaim the account through Marriott Bonvoy’s official flow, kick the attacker out of every session, then close the door they came through — usually a password that leaked in a breach and was reused.
If your Marriott Bonvoy account was hacked: start recovery at the official page (help.marriott.com/s/), change the password to a unique one, sign out all other sessions, and re-check the recovery email and phone on the account. Then find out how the attacker got in — check whether your password appears in known breach data — and turn on two-factor authentication so it can’t happen again.
Recover your Marriott Bonvoy account, step by step
These steps follow Marriott Bonvoy’s official process. Official links only: account recovery · password reset.
Reset your Bonvoy password (make it unique) from the account login page.
If contact details were changed, contact Marriott Bonvoy support and report account takeover with your member number.
Review award reservations, points transfers and free-night certificates; remove unknown saved cards.
Request reinstatement of stolen points and cancellation of fraudulent stays; enable available login alerts.
What trips people up with Marriott Bonvoy
- Bonvoy points and free-night certificates are cashed out via award stays booked for strangers - review upcoming reservations and points activity, not just whether you can log in.
- Marriott has had large historical breaches, so credential stuffing against reused passwords is the common entry - a unique password matters more than anything else here.
Still logged in? Lock the account down now
If you can still get in, you're racing the attacker. In this order: change the password to a long, unique one; sign out all other sessions/devices (the setting exists in Marriott Bonvoy's security settings); confirm the recovery email and phone number are yours (attackers quietly add their own so they can "recover" the account later); remove unfamiliar linked apps or API access; and turn on two-factor authentication. Only then deal with anything the attacker posted, sent or bought.
Locked out of Marriott Bonvoy — email or phone was changed
This is the worst-case scenario and the most common complaint: the attacker changed the account email, phone number or password so the normal reset flow emails them, not you. Do NOT keep triggering password resets — they go to the hacker. Go straight to Marriott Bonvoy's dedicated recovery flow (link above), which is built for exactly this case: it verifies you by your original signup details, previous passwords, linked devices or a government ID / selfie check, bypassing the stolen email. Watch for the security notice Marriott Bonvoy sent to your OLD email when the address was changed — it usually contains a "revert this change" link that works for a limited time and is the fastest way back in.
Got a "new login" alert from Marriott Bonvoy?
Treat it as real but verify it the safe way: never tap the link in the message itself (fake login alerts are a top phishing template for Marriott Bonvoy). Open the app or type the address yourself, check the active-sessions list in security settings, and if you see a device or location you don't recognize, sign it out and change your password immediately. If the alert was genuine, that password is burned — assume it's circulating and change it everywhere else you reused it.
The attacker spent, moved or stole miles, points or free-night certificates
Document everything first (screenshots of orders, trades or transfers, with dates), then report it through Marriott Bonvoy's official support flow — platforms restore fraudulent purchases and stolen miles, points or free-night certificates case-by-case, and a clean, dated report is what gets approved. If a card or bank account was charged, dispute the charges with the issuer as unauthorized. Change the password on the email account attached to Marriott Bonvoy too — if the attacker owns your inbox, they'll just take the account back.
Why this happened — and how to make sure it can’t again
About a third of account takeovers are credential stuffing: a password you used on Marriott Bonvoy (or the email behind it) leaked in some other company’s breach, and attackers replayed it here automatically. The FBI’s IC3 logged over 5,100 account-takeover complaints with $262M in losses in 2025 alone (IC3). Even when Marriott Bonvoy itself was never breached, your reused password from another site opens it.
So after recovery, check what’s already out there: our free scanner shows which known breaches and dark-web dumps include your email — and whether passwords were exposed with it.
Check my exposure — free →After you recover: three doors to close
- Unique password + 2FA. A password manager plus app-based two-factor stops both stuffing and phishing replays.
- Reset everywhere you reused that password — email first (it’s the master key), then bank, then the rest.
- Shrink your public footprint. Attackers research targets on data-broker sites (your address, phone, relatives — enough to social-engineer support lines). Our free opt-out guide covers 190 of them, step by step.
Hacked Marriott Bonvoy account, answered
How did my Marriott Bonvoy account get hacked?
The most common cause isn't a hack of Marriott Bonvoy itself — it's credential stuffing: a password you used on Marriott Bonvoy leaked from some other site's breach, and attackers tried it here automatically. Roughly a third of account takeovers happen this way, with phishing (fake Marriott Bonvoy login pages and alerts) close behind. That's why the first fix is a unique password, not just a new one.
Can I get my Marriott Bonvoy account back?
Usually yes. Use the official recovery flow (https://help.marriott.com/s/) — it can verify you even when the attacker changed the email and password. Be patient and respond quickly to follow-ups so the case stays open.
Should I just make a new Marriott Bonvoy account instead?
Not until you've tried recovery. The old account keeps your history and contacts — and while the attacker controls it, it will be used to scam people who trust you. Recover it, or at minimum report it as compromised so Marriott Bonvoy can lock it, before you start over.
How do I stop my Marriott Bonvoy account being hacked again?
Three things close most of the doors: a unique password (a manager makes this painless), app-based two-factor authentication, and shrinking your exposed footprint — checking your email against known breach databases and removing your personal data from data-broker sites that attackers use to research targets.
