Questions about each
Mysterium VPN
What does Mysterium VPN cost month to month and on a long term plan?+
The monthly plan costs $10.49 to $18.49. Longer commitments are cheaper per month, with the long term plan at $2.59 to $4.79 and the longest term running 24 months. Both figures sit above the €7.89 monthly median for the category, so the saving comes from committing rather than from a lower opening rate.
How many devices can one Mysterium VPN account cover?+
One account covers 15 devices, and the plan places 1 of 80 brands on that measure. For context, the median device allowance in the category is 7, so a household with a phone, a laptop, a desktop and a browser extension stays inside the limit.
Which platforms does Mysterium VPN run on?+
Apps are published for Android, iOS and macOS. The browser extension matters for readers who want the tunnel in Chrome rather than a system wide client, and the same account carries the mobile and desktop apps, so one plan covers all of them.
Proton Pass
Which platforms are listed for Proton Pass apps?+
The provider lists Android, iOS, Windows, macOS and Linux.
