Solution 10636: Cannot Log Into the Texas Instruments Website.
Why do I get an error when I attempt to log into My Account on the Texas Instruments website?
To download free Calculator Software Applications (Apps) or to purchase items on the Texas Instruments online store, an account with the Texas Instruments website is needed.
When a user does not have an account or logs in with wrong email address and password, this error message will show up:
"Invalid username and/or password."
Please make sure to enter correct email address and password. If the password is forgotten, request the password by clicking on [Forgot Password?]. To keep information private, the password will be reset and the Login information will be sent to the email address in the profile.
If an individual does not have an account, please click on Create Account and choose to either register as an individual or a user of an existing company.
If you require additional assistance please contact TI-Cares.
