If security is a concern, using an encryption key rather than a long password would be preferable. You could encrypt your data with PGP encryption and send yourself the encryption key later. That's beyond the subject and a bit complicated but it might interest you. You can use a cryptographic key simply to increase the complexity and make so that it is not accessible via simple brute-force. Basically doing your setup twice in 2 completely independent ways with no single point of failure.Įncryption has to do with security, not time.

Redundant could mean having two or more files with the data, with two different passwords, on 2 different hard drives, with two different remote email services from 2 different companies. The important thing is being sure that that external service is reliable and redundant when the time comes so that you don't lose the info forever. Having and external service to send you a message at a certain time is the answer I believe. So somebody else would have to run the clock. Anything that reboots either has to be told the time or can be updated with new time info. The problem with a windows or local solution is that you can change the time or fake an ntp server. If it's under your control, you can "hack" the time. The problem is that you have to rely on gmail.įuture mail: gmail calendar, lettermelater. No 2 factor authentication, no way of getting back in.

Get it to send you a cryptographic key or to send you the password at a time that is programmed in the future. Put a crazy password on gmail (or any email service that you expect to still be in business when the time comes). You could set up an remote email account and throw away the key.
