Often I end up doing server administration for clients as part of developing web applications, I always set up access for myself using an SSH Key pair. I usually end up choosing a random password for the root account and emailing that to my clients. The client sometimes doesn't even need to have access, I just want to make sure and not be the only one holding the keys in case I'm not available, or they switch to another developer.

For non-technical clients, what is the best way to manage, store, and communicate important passwords and credentials?

Personally, I use Lastpass, but requesting a client to signup to share one password which can't be used via the browser seems a little off.

If I am the sole admin in an organization and nobody else has the technical skill or inclination to manage the systems my personal preference is to demonstrate that the passwords work, then give them to the client on paper, in a break-open box (I use KeySure boxes

If I am hit by a bus, quit, or get let go all they need to do is break open the box and they have all the passwords I've set/changed.
If I'm still around and I notice that the key box has been broken open I know someone has the passwords who shouldn't (or someone who should have them is touching stuff without telling me) -- This offers some protection from well-meaning folks trying to "fix" a problem and destroying a stable environment.

In larger companies like the one I'm at now the back of our Site Operations book contains a page of (PGP-Encrypted) passwords for stuff that does not use key-based authentication. The passwords are accessible to the C-level officers of the company, as well as the senior admins & developers, either by cutting and pasting from a PDF of the Site Ops book or in the absolute worst case by carefully re-typing the encrypted block.

Link for does not seem to work... I think this is what voretaq7 is referring to: – BillN Jun 23 '10 at 16:38
Hmm - works for me... I'll edit & long-link it (but yes -- same product :-) – voretaq7 Jun 23 '10 at 16:49

You could use something like a password-protected .ZIP file through with a one-time download and expiry date. You could call and give them the password for the zip and dropbox over the phone and email them the link.

I've also text messaged or phoned half of the password, email the other half, or some combination of both.

Since it looks like you've rephrased your question, if you're on-site, I would grab a copy of KeyPass and install it on a USB key or on their server. It uses Blowfish encryption, doesn't require installation, and can store all of their passwords in one secure place.

Rephrased my question? It hasn't been edited. Unfortunately, I'm not on site, I'm not near my clients. – Daniel Beardsley Jun 23 '10 at 20:04
Either that or I wasn't paying attention the first time around. – WuckaChucka Jun 23 '10 at 22:44

Skype IM uses encryption so if your client uses that, that might work for you.

Funny. You recommend a closed source software with no detail about the used encryption algorithm. And where NSA, DoD and others have hooks into the system to intercept all communication. – mailq Jan 27 '12 at 23:58
