What’s the best way to only allow a file to be opened with multiple people’s authorisation?
Is there software available that makes it easy for multiple authorisations to be required before a file can be opened? The simplest solution I've found online is to encrypt a file with a password, split the passwords into multiple pieces and give each user a password fragment, but this requires them all to be physically present or log in remotely to type their segment of the password if they're going to enter it without revealing it.
The ideal way might be to provide some kind of temporary code, something like TOTP, which could then be sent to open the file on a given occasion but wouldn't be useful thereafter.
Is there an easy way to do something like this securely?
