Proton's centralized login fails, blocking access to Mail, VPN, password manager, and crypto wallet

Proton declared an incident at 15:35 CEST on July 10, 2026, affecting login across its entire service portfolio: Mail, Calendar, Drive, Pass, VPN, SimpleLogin, Wallet, and Lumo. The simultaneous outage across disparate products points to a failure in Proton's centralized authentication layer rather than isolated service faults. Users relying on Proton Pass for passwords and Proton Mail for email lost both at once. As of 15:42 CEST, Proton's teams remained investigating with no resolution posted.
