We use the highest client-side available hashing standard for all user data. If you suspect that any of your accounts got compromised, change all of your passwords immediately. We encourage every user to handle their personal data carefully. It's recommended not to re-use a password, instead consider using a password manager. Don't share your private data with anyone. Use long hard-to-remember & highly randomised passwords. Also add additional security to all your accounts via 2FA, if possible.
