If so, you'd better change your passwords, because Toys R Us had a data breach:
Toys''R''Us has many layers of account security in place to keep your Rewards''R''Us balance and other profile information safe. Recently, we identified an attempt to gain unauthorized access to a small percentage of Rewards''R''Us accounts from 1/28/15–1/30/15. We suspect this activity was due to large breaches at other companies (not Toys''R''Us), where user login names and passwords were stolen and then used for unauthorized access to other accounts, such as Rewards“R”Us accounts where a user may use the same login name and/or password.
