Password storage

Even better then onetimesecret.com. With safenote you can even upload any file up to 100MB. I've used this to share passwords without email or an app needed. Information gets automatically destroyed after one view of after a max of 30 days.

I can vouch for the security. Offline, fully-encrypted vault with the options to sync with popular vendors. No information stored on the companies servers. No way to retrieve your master password if you forget it. No incredibly fancy fill-in alike other platforms, just security and functionality focused.
