About Security & Privacy Tools
Doffl security and privacy tools help you protect accounts, files and personal data. Generate strong passwords and passphrases, check whether a password has appeared in known data breaches, store two-factor backup codes, create hashes and checksums, and encrypt or decode text. Privacy tools remove EXIF metadata and GPS location from photos before you share them, while network tools check SSL certificates and security headers on your website. The tools are designed for individuals, IT admins, developers and small businesses that want simple, reliable protection without installing extra software. Sensitive operations run in your browser so secrets never leave your device. Choose a tool, follow the clear steps and keep your digital life safer. Regularly updating passwords and removing photo metadata are two simple habits these tools make effortless.

Frequently asked questions
Is it safe to check my password online?
The breach checker uses a privacy-preserving method that never sends your full password. Generated passwords are created locally in your browser.
Where are my backup codes stored?
Backup codes are stored in your secure Doffl account and are only visible to you after signing in.
What is EXIF data and why remove it?
EXIF is hidden photo information such as camera details and GPS location. Removing it stops others from learning where a photo was taken.
Are the security tools free?
Yes. Core security and privacy tools are free to use.
