Abstract: A system and method for automatically merging accounts based on matching email addresses and passwords, is provided. The assumption made is that two or more accounts that have the same user identifier or ID (e.g. email address) and the same password belong to the same user. Generally, in order to log into an account, the user requires is a user ID or username (e.g. an email address), password and store ID, for example URL. Typically, plaintext passwords are not stored centrally for security reasons, but instead hashed passwords are stored. When a user logs in with a plaintext password and username, the plaintext password is processed as it would be for other accounts with the same user ID, to see if the password works for those accounts. If it does work, then the same plaintext password applies, and the accounts are automatically merged.
