Is it a good practice to share one dao accross multiple files that use it?

Question

I have an entity

User

If I want to make an operation with this entity I use

UserDao

Is this a good practice to have only one instance of this dao in whole solution shared accross the project and files whenever it is needed?

Like having this dao in a singleton?

thanks for answers
