Need To Change Developers Acct To Windows Authentication

I have my SQL 7.0 server set for Mixed security. I see now (finally)
the advantages of having windows authentication security for windows
groups.
I do most of my developing in Access Projects which require a login of
some type. I have been using my SQL login to develop with SQL and
then when I give it to the user, I set the project to use Windows
authentication. I want to be able to have Windows authentication on
my domain account but the user name for my windows account is the same
as my SQL account and it won't let me change the existing account.
Now what happens is after I develop the product I have to have the
user login and go in and change to windows authentication. It won't
let me do it with my sql account.

I fear that if I delete my sql account and create a windows
authentication account all the views, sps, etc. that I have created
will still have the reference to the sql login and therefore not work.

Do I need to have a generic sql account for developing? One thought I
had was to create a new domain account so I can create that windows
login and at least get my most recent projects working like I want to?

Hope this makes sense to someone.
Thanks in advance for your time.
