What features are you considering essential in a password manager app?

Hey,

My name is Kevin, I'm the co-founder of 2Stable, 2Stable is a company that develops privacy-focused services. At the moment we have started working on a password manager app exclusively for Apple devices and I would appreciate your help if you could share your opinion, on what features you would like to see in a password manager app?. More than this, what features are you considering essential for a password manager app?.

Thanks in advance
