It's also the only one I could possibly forget, cause I obviously don't know any of the randomly generated ones. I probably never even seen 99% of them ever. Blissful ignorance
After that disaster with LastPass I'll never trust any password safe anymore, keepass, self hosted, but that's just me. Plus: you have to type the password so often in the beginning and during config, you'll never forget it ;)
If you saved the master password in BW as well and have it installed on another device like a phone, would it work to put the phone on airplane mode before opening the app so the vault doesn't refresh? Also, does changing the master password automatically remove the pin lock so you're forced to use the master password to get back in?
Yes, if it disconnected and is unable to sync, you can still access the vault.
If you change the master password elsewhere, when your app is able to sync, it will log out automatically.
Ideally, since you want to write your master password down to keep it safe somewhere (because you can forget), you write the new password down before you change the password.
