2. The method of claim 1 , wherein the generating is repeated for each initiation of the web service.

3. The method of claim 1 , wherein the generating is repeated to produce different real-world placeholder data for each initiation of the web service.

4. The method of claim 1 , wherein the one or more initiations for the web service comprise gesture data.

5. The method of claim 1 , wherein the generating comprises selecting a real-world placeholder format.

6. The method of claim 5 , wherein the real-world placeholder format conforms to an email address format of an email provider.

7. The method of claim 1 , wherein the generating comprises employing a characteristic of the user in selecting the real-world placeholder data.

8. The method of claim 7 , wherein the characteristic is system generated.

9. The method of claim 7 , wherein the characteristic is a demographic characteristic.

10. The method of claim 7 , wherein the characteristic is user supplied.

11. The method of claim 1 , wherein the one or more initiations for the web service comprise gesture data.

12. The method of claim 11 , wherein the employing the real-world placeholder data in an automated sign-on process to the web service is conditioned on receipt of the gesture data.

13. An electronic device, comprising:

a processor; and

a memory that stores instructions executable by the processor to:

receive, from an end user device, authentication data of a user of a web service;

store, in a single sign-on service, the authentication data;

receive, at the single sign-on service, one or more initiations for the web service;

19. The electronic device of claim 16 , wherein the characteristic is user supplied.

20. A product, comprising:

a storage device having code stored therewith, the code being executable by a processor of an electronic device and comprising:

code that receives, from an end user device, authentication data of a user of a web service;

code that stores, in a single sign-on service, the authentication data;

code that receives, at the single sign-on service, one or more initiations for the web service;

code that generates, using a processor, real-world placeholder data for the user; and

code that employs the real-world placeholder data in an automated sign-on process to the web service.
