Is it possible to reset the encryption key?
What happens if we loose it?
I can't set labels so I added # in the title
No, it's not possible to reset encryption password without knowing the password.
@wwebfor: ok, it makes sense! But I've cleaned my cache and I still can't get into Laverna in FF.
Did you clean your cache to remove everything and start over? If yes, then you need to remove IndexedDB database to start over:

:clap: thanks! It worked!
You might want to add that to the Readme for the next person having this question.
i had the same problem but i didn't know how to clean the cache or even indexedDB, can you help ?
@mhmoodlan as it's written above after cleaning your cache you need to remove IndexedDB database.
In the console type:
indexedDB.deleteDatabase('notes-db')
i am using the windows app not the browser one, is that what i should do too in this case?.... i'm new to this electron thing so please be patient with me.
@mhmoodlan you can try to remove %USERPROFILE%\AppData\Local\Chromium\Laverna folder.
@wwebfor okay so which folder for linux ?
@hckweb ~/.config/chromium/laverna
@wwebfor which folder is for mac?
@katwekibs I fixed my problem under mac with rm -r ~/Library/Application\ Support/laverna/IndexedDB/
@wwebfor Thanks, I am using Windows10 x64, and I found that folder in %USERPROFILE%\AppData\Roaming\Laverna instead of %USERPROFILE%\AppData\Local\Chromium\Laverna.
Hope this can be used as reference.
