I started using Keepass and changed all my passwords to auto generated passwords. Somehow, my PC crashed before I saved the database. That was the day, where I lost access to my primary email address.

No backup email address set for password recovery on your email?

This... This right here is why I won't use password storage solutions that don't have an automatic backup of some kind, whether it's to my own server or a secure cloud server I don't care so long as it's encypted and only my password can decrypt it.

@gitlab or and it's a lesson so save as often as possible

@gitlab did you just say 'secure' and 'cloud' in one sentence without negation?

Just use lastpass. Or Dashlane but I find lp better than dl from recent experience for the price.
