|Issue||This article provides information on how to resynchronize a SecurID hardware or software token from the Authentication Manager 8.1 Self-Service Console.|
To resynchonize the token,
3. On the Troubleshoot Your Token Page, choose Other or Not Sure and then click OK.
4. On the Confirmation Required Page, click Yes to confirm that the token is not damaged and can still generate tokencodes.
5. On the Resynchronize Token Page, do the following:
|Notes||Token synchronization checks the current UTC server time then reviews all possible tokencodes, plus or minus 12 hours from the current server time to find two sequential tokencodes that match what was entered.|
With this process the Authentication Manager server determines how fast or slow the clock in the token is as compared to the server clock, which is assumed to be connected to NTP and accurate. If the server determines that the tokencodes provided during the synchronization process are correct but either for a time in the past or the future, the token offset table is updated with the offset value. The next time the token is used for authentication the offset value is used to find the correct tokencode value for that minute to determine if authentication is successful.
A token synchronization will fail for one or more of the following reasons:
