I have the same problem.
If you have set a password for the secure credential storage you need to do this each time you restart the phone. If you do not use the secure credential storage you can perform "Clear all credentials" to get rid of this issue.
I contacted HTC regarding this issue and was asked to perform a factory reset. This did NOT help.
