Act quickly
Start here: how can you reach your account?
Don't assume you're locked out
Path 1 — Recover from the Yahoo Mail app (your best hope)
Open Account security in the app
Reach your security settings from the device that's still signed in:
- Open the Yahoo Mail app and tap your profile icon to open Accounts
- Tap Manage accounts, then Account info under your account
- On the Account screen, tap Security
- Confirm with your fingerprint or face when prompted — that passkey is what proves it's you, so you get in even if the password was changed

Change your password
You're in your account — now reset your password so the attacker's copy stops working:
- On Account security, under Ways of signing in, tap Password
- Enter a strong, unique new password and tap Continue
Because the app already verified you, it won't ask for the old password. Changing it locks the attacker out of the front door.

Sign out of all other sessions
Changing your password doesn't always end the attacker's existing sessions, so force them out:
- On the same Security page, scroll down to Current sign-ins
- Tap any session you don't recognise — Yahoo flags unfamiliar ones as Unrecognised — then choose Sign out and confirm
- Repeat for every session that isn't yours, leaving only your current device
While you're there, check the listed locations and devices for anything unfamiliar.

What's a current sign-in?
Where you're signed in to your Yahoo account. Sign out of any you don't use or recognise.

You're not out of the woods yet
Path 2 — Recover online with the Sign-in Helper
Start on a device you've used before
Before you go near the recovery page, pick up a device and browser you've signed in with before — ideally on your home Wi-Fi or your usual mobile data. Yahoo trusts familiar devices, browsers and networks far more, and that can be the single biggest factor in getting back in.
Open the Sign-in Helper and verify it's you
Recover the account and prove it's you with any recovery option you still have — the more you can reach, the better your odds:
- Go to login.yahoo.com/forgot and enter your Yahoo address, then Continue
- Pick whichever option you can still access — a code by text (SMS) to your recovery phone, a code to your recovery email, or a Yahoo Account Key prompt on the app
- Enter the code (check spam and junk for the emailed one) and continue
A successful code signs you straight back in — Yahoo drops you on your homepage rather than forcing a password reset, so you'll change your password yourself in the next step.
If you turned on two-step verification (2FA), the Sign-in Helper may offer a different set of options — such as an authenticator-app code or a sign-in prompt — rather than just SMS and email. Use whichever second factor you set up; if you've lost access to that too, work through the fallback below.
Sign-in Helper
Enter your email or recovery phone number and we'll help you back into your account.

Change your password now
You're back in — but don't stop here. The Sign-in Helper let you in without resetting your password, so the attacker may still know the old one. While you're still signed in, change it before anything else:
- Click your profile icon (top-right) and choose Manage your account
- On the Overview page, under Looking for something else?, click Change password
- Enter a strong new password and click Continue
Make it long (16+ characters), unique to this account, and saved in a password manager — a fresh password the attacker doesn't know locks them out of the front door.

- Move your other accounts over. Anywhere you used the old address to sign in or to reset passwords — banking, shopping, social media — change that password and set your new Proton address as the account email and recovery contact, so the lost inbox can't be used to take them too.
- Warn your contacts. Tell friends, family and colleagues that messages from the old account may not be you, and to ignore any requests for money, codes or links.
- Watch for misuse. Turn on alerts where you can and keep an eye on anything that was tied to the old address.
