Length and permitted characters
Choose a length compatible with the service and its allowed groups: uppercase, lowercase, digits and symbols. Bivonio includes at least one character from each selected group.
Use a different password for each service. Reuse exposes other accounts when one service suffers a breach; changing a single digit does not create meaningful independence.
Browser randomness
Generation uses Web Crypto and rejection sampling to avoid modulo bias. It does not derive patterns from names, dates or your personal information.
Randomness alone cannot guarantee account security. Your device, storage, service and additional access mechanisms also matter.
- Select groups accepted by the service.
- Choose a length and generate a password.
- Save it in your manager and check that the entry matches the right account.
- Avoid sharing screenshots or messages and do not reuse it.
Save before closing
Bivonio does not store the password or recover it after closing or reloading. Confirm it is saved before completing a service’s password change.
The clipboard and extensions belong to your device. Copying a password does not encrypt it; treat the output as sensitive information.
