Create a username with read only access

Hello all,

I have all objects for the project granted to public

and I need to create new username with read only option.

Other than creating a role and revoke all access from public and giving it to role

and give the role to user ,are there any simpler solution????

Because the above need alot of work

1-Create role

2-Grant all object to role

3-Grant the role to requried users

4-revoke public from all usres

then I can create new user with read only access.

I don't feel thats proper solution....

Any Ideas?
