As far as I know you would need to unregister/register the repository but that only takes a very small amount of time.
For greater security, I'd actually suggest changing Laserfiche to run under a windows service account and then grant that account access to the SQL server. If you do this you can change the password on the Laserfiche server whenever you need to by stopping the laserfiche service, changing the password, changing the password in services.msc and restarting Laserfiche.
It's always a debate but the majority of the articles I've seen suggest using windows credentials to connect to SQL server is more secure than using local sql server accounts.
