What will happen to cookies when changing the key?

Question

Laravel

Cookies in Laravel are encrypted using a key in the .env file.
If the key is changed (artisan key: generate), then the old cookies will remain, but will not be available?

Answer 1

If you are using the site at this moment and, for example, are logged in, then after updating the key, you will be logged out and an error may appear that the token is lost.
