I've traveled domestically and had the Steam Deck randomly decide that the games I preloaded need to be authenticated again because I didn't explicitly put the device in "offline mode" before traveling. A GOG game sideloaded through Heroic would just work.

This year I was in three foreign countries with my Steam Deck. Once per flight, the other two by car. On the plane I activated airplane mode because duh but outside the plane airplane mode was always off.

By default Steam downloads shader caches off Valve's servers. So if Steam saw before that an update is available and you didn't download it, Steam wants to be online to download them. You can disable shader cache downloads in desktop mode but then the games have to compile the shaders by themselves which takes time computing resources, and in turn wastes battery power.

Also, pretty recently there was a bug in Steam that messed up authentication in general. It required me to log in twice (!) on every power on. The bug is now gone. It wasn't a feature.

Yeah, this is the gist of the problem. When a PC is connected to airplane WiFi, but it is limited, Steam decides it is online, but some sort of validation fails and then no games will play until I get back to a full internet connection and reboot. I don't even try anymore, hence my comment about GOG, and yes, I know some games on GOG have DRM, but most don't and they don't hide the fact. The Steam DRM bootlicking combined with GOG hatred because they were forced to sell a few games with DRM is so bizarre. Are Steam fan boys a thing? What a weird hill to fight for.

DRM is the heart of most technology pain for paying customers since it's inception. For pirates, the experience is much better since the DRM is removed.

Nope, this is something different. I booted up Metaphor: ReFantazio, and it just about made it to the main menu before telling me I needed to be in offline mode, but you can't explicitly put the device in offline mode if you don't have an internet connection, funny enough. Fortunately I was on an Amtrak with Wi-Fi, but I shouldn't have needed to do that. As far as I can tell, the reason I needed to authenticate the game again is because the Deck ran a "validating install" step on boot, but I have no idea when that step is going to happen, and once again, I shouldn't have to plan ahead for being offline.

Sounds like a game bug.

"..." button --> Airplane mode.

When you do something to bork the game data. It's either user error or a bug but definitively not regular behaviour.

It's not a game bug; that's Steam's DRM.

Airplane mode is not offline mode. I found that out explicitly this year due to how Ubisoft's launcher interacts with playing offline in Prince of Persia: The Lost Crown. Offline mode is found from the Internet menu in the Steam Deck interface and is very much not the same thing as just not having an internet connection, as much as that would make sense.

I didn't break any game data. This is an OS level feature, and it just does it sometimes on boot. I'm glad you've never been inconvenienced by these things yourself, but this is the intended functionality.

Funny how you got hit by that on an domestic train trip and I traveled abroad several times and not got that weird behaviour even once. I simply never use offline mode. On the plane I was in airplane mode and when not on the plane I was on hotel wifi, personal phone hotspot, or just not connected to any wifi. Steam also never just out of the blue validated my game data. Must be a problem on your end.

No, it's really just a luck of the draw thing on boot.
