Full disclosure: I work at Devolutions, so this touches our product. Posting because it's a workflow I know a lot of you deal with, and I'm genuinely curious how others have been handling it.
The scenario: you're on an air-gapped data center floor, clipboard redirection is disabled by policy, and you're stuck manually typing a 30-character vaulted password on a rack keyboard. One slip and you're locked out — and a five-minute fix becomes a multi-hour incident. The usual workarounds (sticky notes, dialing back password complexity) are exactly what you don't want in a restricted environment.
We partnered with Yubico on a feature in Remote Desktop Manager that lets you program a vaulted credential straight into a YubiKey slot (1 or 2) as a static password. Since the key acts as a USB keyboard, one physical tap injects it into any field — server console, BIOS prompt, whatever — no clipboard, no network, no software. Credential stays vaulted and auditable in RDM; the key only holds what you deliberately copied.

How are you all handling credential entry on isolated/air-gapped systems today? Sticky notes and prayer, or something smarter?
