Yes.
Yes.
You can not. The team at Bitwarden also can not. That is the reason why Bitwarden is so secure. To avoid this kind of desaster follow these recommendations:
- Keep a copy of your password in a secure place.
- Make backups of your data.
- Take a look at their “Emergency Access”-feature
- For your Master Password stick to the characters that are available inside their password generator.
You are welcome
