@matrix2280 The behaviors you are seeing are occurring because you are using the default settings for URI Match Detection. The default detection method is Base Domain, which means that any of your stored login credentials for vault.bitwarden.com or community.bitwarden.com will “match” (i.e., be auto-fillable) on any webpage on the bitwarden.com domain — including https://bitwarden.com/password-generator/.
To fix this, change the match detection option by editing the login item in your vault and clicking on the gear icon (
) next to the stored URL, which displays a drop-down menu of match detection option. Change the setting from Default to Host for your both of your Bitwarden login items, and save. Now, you can go to any bitwarden.com site without autofilling your master password or community forum password in the wrong location.
