How important is "try without an account" for a SaaS service?

Hi I am working on improving the "try without an account" functionality for my projects; I was curious about your experience. The most recurrent feedback/comment that I had from possible users is that it would be nice to try the service without an account, so I am focusing on this. Do you consider this a nice to have or a key functionality? How much priority do you give to this? Did you see a significant change when you implemented this? Thank you, let me know your thoughts
