Steps to Reproduce

1. Run coder login https://my.production.server
2. Decide to debug code server with code server --dev
3. Observe production credentials are overwritten

Expected

It would be nice of coder server --dev asked for confirmation before overwriting.

Actual

Notice after the fact that regular credentials have been overwritten.

Notes

This is working as-intended, but I think it'd be good for us to consider what the end-user behavior should be.
