I'm off to change my email passwords. I may be some time.
If you have concerns, please check on the website that checks for this - link here or you can check for a site called 'have I been pwned?' As far as I can tell with my meagre skills, it's safe.
It's about time I changed my passwords, and I'm thinking of setting up a reminder to change them on a regular basis. You really cannot be too careful.
