Opassum (English)
Opassum is quite like NoteSV. Both are password managers. Opassum.com works as a website, NoteSV instead is a desktop/mobile application. I've used both of them for some time now, so:
❎ Opassum isn't as cheap as NoteSV. Creating a new "vault" for credentials to be stored inside costs maybe 1 USD -- I don't remember. Besides that each time a new item is stored, Opassum needs something like 0.1 USD to store it on chain. Opassum does indeed store items inside the Bitcoin SV (BSV) blockchain, but the contents are encrypted.
✅ Opassum.com has a nice export feature where contents belonging to users' vault can be backed up. It also has dark theme, which is nice. 😊
