How is your credit score affected if married and have joint finances?

This might be dumb lol but I’ve never really thought about it. I’m working on building my credit score. Im not engaged or anything, but if I get married in the future, I’d like to know how this would affect my credit score.

For an example, if we purchase a home using a mortgage, and it’s in both of our names, does that have an effect on both of our credit scores? It probably does and it’s really obvious, but maybe there is something I don’t know about.

If you’re married, is your credit score similar to your spouses?
