You should ~~probably~~ definitely change your password.

Don't just change it, make it unique and keep it that way for every account there should be a unique password to go with it, if you can't think of one try remembering three random words or use a password manager like Keepass or Bitwarden both open source and very popular. https://www.youtube.com/watch?v=aHaBH4LqGsI
