How are you storing passwords and 2FA keys that proliferate across every conceivable online service these days?
What made you choose that solution and have you considered what would happen in life altering situations like, hardware failure, theft, fire, divorce, death?
If you’re using an online solution, has it been hacked and how did that impact you?
See my follow-up post elsewhere here. Sounds like you might not have an always-online device to keep others always synced, and/or the devices you’re using to add entries aren’t online when you do. Might consider using a designated device for database modifications.
