Firstly, I was unsure to create an issue or ask here before. So if you prefer the former, I can also do that.
I probably have set the Encryption key settings for my vault a bit too strong, which means on weaker machines, unlocking might take up to a couple of seconds. But I am completely fine with that.
The only problem I noticed, is that if the master password is set to be visible while unlocking, it stays visible during the whole process. The Toggle visibility button does not work while unlocking and the UI is unresponive. This might be seen as rather opinionated, but I think it should be set to be hidden before unlocking. In most cases, unlocking is probably fast enough that you won’t notice it anyway.
I have only noticed this on the desktop clients on Windows 10 and Kubuntu 22.04, but never tested it anywhere else (browser, etc.).
Admittedly, I rarely use Toggle visibility, but still, is there a way to hide during unlock, that I am not seeing?
