While accessing the Symantec Endpoint Protection Manager (SEPM) Web Console, if the tab key is pressed to enter the password after typing the "User name", only the first character of the password gets typed.

Known Issue
This will be fixed in a future release of SEPM.
As a workaround, the cursor/mouse needs to be clicked to type the complete password.
