Track record
No known breaches
- Known data breaches
- ✓ None on record for t-online.de
From public sources, last read on 31 October 2026: breaches from Have I Been Pwned (CC BY 4.0), which lists breaches of the provider's own site, not of every account that uses it; incidents as the provider reports them. None of this changes my stars.
