Best protection for your password secrets!
This product is under constant development.

Despite the huge range of functions, the user interface appears tidy and clear. Those who want to save the password database in the cloud or on a web space can choose the standard Strongbox version. And for those who prefer a version without online features, Strongbox Zero is the ideal choice.

Great: in addition to the subscription versions, which are unfortunately necessary for developers nowadays, there are also licences available for a one-off payment, because not everyone likes subscriptions.

I like the fact that you can give a tip as an in-app payment!
This way you can also say thank you occasionally as a one-time payer.

There are many good password managers and the main thing is that you use one! Demands and tastes are different and whether you like this or that password safe better also depends on what you used to use. Those who have used KeePassB on a BlackBerry Playbook or BB10 smartphone may prefer Andrei Popleteev's KeePassium – out of habit.
I had tried both and I had liked Strongbox better from the beginning, although its user interface was not as nice as it is now.
And then came the offline version Strongbox Zero – perfect for me!

Unless you only use Apple devices, this is not an obstacle. The KeePass database file is compatible with KeePass password managers for Android, Linux and Windows.
On Fairphone 3+ and Fairphone 4 5G, I used KeePassDX and exchanged the password files with those for Strongbox on iOS and macOS as soon as something changed. I had also exported the password file from Strongbox Zero and loaded it into KeePassDX on my new Pixel 7 Pro.

Since I had set up two user profiles on the Pixel 7 Pro, manual synchronisation became too cumbersome for me. That's why I tested the only platform-independent open source solution Bitwarden. It is permanently free for private individuals (TOTP only for the master password).
In the meantime, I also added the Pixel 8 Pro. Bitwarden has proved its worth for my zoo of devices and is convenient and secure.
