If you received a notification that the email address for your Dropbox account has changed, first verify that the notification really came from Dropbox.
If it's genuine, and you didn't make the change, contact us. Please note that changing the email address for a Dropbox account requires the password. If you shared the password with someone else, or you shared your email account with someone else (which would have enabled the other person to reset the password to the Dropbox account), we might not be able to take any action on your behalf. Regardless, here are some things you can do right away:
- Try signing in to the account with the new email address and the last known password. If you can still sign in, you can change the email address back to yours (and then change the password).
- Secure your email account by changing the password for it. If your email provider also offers two-step verification (also known as two-factor authentication), we recommend that you enable that security feature as well.
- If your computer is still linked to the account through the Dropbox desktop application, or the computer has your Dropbox files on it, you can create a new account and link your computer to the new account. The files will be uploaded to the new account.
