Snapped my second ever chain
In all my years riding I've only had one chain snap on me. Last weekend I had a second. I was on my mtn bike and did a somewhat poorly timed shift under load. I didn't think it was too much load and I've certainly made worse shifts over the years. But somehow the stars aligned and the chain snapped. Luckily no injuries. I carry a Oneup EDC multi-tool which has a chain breaker. It's the V1 version of the tool and I remember reading somewhere how the weak point of the thing was the chain breaker. But, it did a fine job cutting out the broken link and letting me join the remaining ends together. The chain was too short to handle the low gears, but at least I was able to gingerly pedal out. Chain was a waxed YBN 12spd with about 350 mtn miles.

Glad you could do an on-trail repair. I broke one about 30 years ago, two blocks from a bike shop. They wouldn't let me use their chain tool and I didn't have any money on me, so they wouldn't fix it on a "promise". Never went back to that bike shop. Not my current location. I threaded some string through the chain ends and limped home, amazing I even made it.

That's pretty lame that the shop wouldn't help out.
I've been rethinking the repair and one other thing I remember was how easy it was to push the pin out. There's a chance I might've gotten the chain on Amazon and now I'm wondering if I got a counterfeit chain.

It’s probably a good possibility.
I bought a couple of chains through shady channels during the peak pandemic shortages and one measured out at full stretch in under 100 miles! Almost certainly a fake. Also recently got burned on fake shimano pedals. Lesson learned and I buy that kind of stuff now only through authorized distro channels. Glad you didn’t get hurt and were able to limp home!

In the late 80s, I had a MTB with 7 speed XT and I broke two chains and a RD, which I think broke due to the chain. The first chain broke on a fast descent and I couldn't find it. The second one broke in the parking lot of my apartment, and snapped the RD. I went with Sachs chains after that. I carry a SRAM 12 speed link and a Shimano 11 speed link in my saddle bag. I think they have protected me from broken chains. I figure I can use the Shimano link on my campy 11 to get home. FWIW, I never used campy chains on my 10 speed stuff, I used Wipperman or KMC.

I have broken two chains. I generally carry an extra quick link and a chain tool, but one time I was out on my fatbike which was pretty new so I had skipped putting a multitool and quick link in the saddlebag. It actually broke at the quick link. Pretty lucky I noticed the chain giving way, so I didn't go otb. I had to walk over a mountain, about 7 miles. And my fatbike is heavy.
I was really lucky on the other one, we were just riding a short way to the start of a 200km ride and the quick link broke. My riding companion just shortened the chain. I guess I didn't have a quick link that time either.

Just yesterday I saw a thread on Reddit about counterfeit YBN chains and master links from Amazon that had side by side pictures of real/fake.
 Particularly on the master links the difference was obvious but only if you had a real one to compare to. The peening on the pins was different.

I broke a chain for the first time in about 20 years a couple months ago. I was crossing a 4 lane divided highway, stomped on the pedal and chain snapped. Luckily I had enough momentum to carry me across and the chain didn’t fall into the roadway, thereby forcing me to play frogger in my bike shoes to fetch.
This was an 8 speed chain and I only had 10+11 speeds quick link in my kit. Luckily I was able to repair although first attempt I pushed the pin all the way out, so the 2 link shorter chain only allowed small cog use for the remaining 20 miles home. I’m theorizing, since I’m not a masher and chain wasn’t that old that it was weakened recently when the chain had annoyingly on an over shift, slipped past the chainring pin and wedged behind it requiring a lot of torquing of the chain to get it out. When I got home I replaced the chain and removed the chainring pin, added 8 speed link to my kit. Pic of my roadside OR:

This has come up many times before, but this is why I only purchase these types of consumables from my LBS. Chains, pedals, cassettes, etc. It's a few bucks more than eBay/Amazon but you know what you're buying and they are glad to have the business.
This reminds me, time for a new cassette on the road bike...

In my experience, there are two reasons why chains snap: 1 forced front shift under really heavy load, as in on a MTB on a very steep slope, and 2 chain wasnt properly riveted together. That's about it.
In case this happens to you, It helps to carry a mini tool with a chain rivetting option in order to continue the ride, and sometimes a very soft saddle.

Broken mtb chains are common because riding conditions can cause these events to happen. My first broken chain was around 1990 riding a rental mtb to Gemini Arches at Moab. I didn't have a chain tool, but a group of 8 people from CO rode by, had a chain tool, fixed the chain, and I hung out with them for the next 2 days. Great people.
