I'm not new to two-factor authentication (2FA) as a concept, but available options and how they'd fit into a workflow has always felt somewhat opaque. Everytime I've been required to use 2FA, I've used SMS despite knowing how insecure that really is.

GitHub's 2FA requirement is about to lock me out of my personal account, so I figured it's time to get a grasp on this:

• What second factors are available to me and what do the workflows looks like?
  • Preferably these second factors wouldn't require me to sign up for some associated service.
• What are my options for redundancy?
  • Can I have multiple second factors?
  • Where are you supposed to keep recovery codes? (I've read that keeping them in your password manager essentially defeats the purpose)
• What happens if I screw up and lose my second factor? With services that just have password requirements, you can use your email to reset, are there analogous systems for 2FA?

I have a business phone number that I use for work in addition to my personal cell phone number which I’ve had for 20+ years. I’ve always used my work number for anything job-related (colleague contact, vendors, sales reps, networking, LinkedIn, etc) and only provide my personal for, well, personal contacts.

But having had my personal number for as long as I have, it’s very easy to Google my name and find that number associated to me.

My issue is that I’m constantly receiving phone calls and voicemails on my personal number from vendors, sales reps, etc that are either for services we use at my job or from vendors in relevant fields contacting me for various reasons. I realize some may lump this kind of outreach into “spam”, but I want to differentiate this kind of outreach from what I consider true spam (robocalls, phishing, non-work related sales calls like for home internet, etc) which just goes ignored and blocked.

I don’t want to answer every call to correct someone to use my work contact info. I can continue ignoring but it does fill my voicemail and I’m hoping to reduce the number of calls I receive on my cell every day (even if it were to only cut it down by 5). Someone suggested changing my outgoing voicemail message to flag it’s my personal number and any work related messages would be ignored while providing my work number. I think this may be the best approach (though I’d skip providing my work number as I don’t need it to start receiving robocalls). I know I’m not the only one that deals with this (but maybe I’m in the minority rather than a majority) and am curious if y'all have this issue and if so, how you manage it?

Hi all - I need some help troubleshooting my internet and really don't feel like dealing w/ customer service reps. I don't consider myself a tech savvy person, so I'm wondering what this community might know..

I've been having issues with my internet for a while. we have xfinity with a plan that promises up to 1000mbps. I'm lucky if i get up to 250 on a good day. beyond that, we constantly lose connection, or get very slow connectivity. i'm using a Netgear c7000v2 as my modem/wifi router combo paired with a Google Nest Mesh router. My home is roughly 1000 sqft footprint split level. my computer is in a different room, but there's no doors between and about 600 ft from the modem/mesh routers.

i called xfinity to talk about the issue, they said that my modem likely needed to be replaced. the initial modem was also a Netgear c7000v2, but i figured maybe the hardware just burnt out(?) they sent me an xfinity modem, and everything seemed to work great (still not 1000mbps, but definitely better). when I realized they were charging me more than I was willing to pay monthly for a rental fee on the modem, i decided i'd go back out and buy a new modem. i bought a Netgear c7000v2 again, because it should be able to handle those speeds, and to my understanding is a decent enough modem. i also bought a new coaxial cable to double check. but after replacing, my internet is still spotty and constantly goes in and out.

i don't have any device to plug directly into the ethernet cable (because it's 2023...), so i can't pinpoint the issue through that. i haven't had an xfinity tech come out yet, because apparently that takes anywhere from 6-8 weeks to get a visit...

any ideas on what i should do? part of me is convinced that xfinity is throttling my internet because I'm not using their modem and paying them a rental fee, but i don't want to give into conspiratorial thinking...i'm about to file an FTC complaint on them because I'm just fed-up at this point.

I haven't really messed with printers in probably 15 years or more, but it felt like any time they were brought up, there were two flavors:

• Older printers, which decided if they wanted to work or not based on absolutely nothing at all
• Newer printers, which are covered in DRM and mostly a nickel-and-diming scam

Now, for the former I remember having some issues, but generally just clearing the printer's cache (or whatever it was called) would fix most of the problems. I think the bigger issue is that I always helped people set up cheap Walmart-sold inkjet printers that had more hardware issues than software, along with ink that would go to shit instantly.

But I was out today at a thrift store and they had a Brother for $25, with an entire extra unopened toner cartridge (I think that's what it's called?). I asked them if it worked, they said it did, but if it didn't I could return it by tomorrow.

So I brought it home, assuming something would be wrong with it, but in about 10 minutes I had it plugged in, connected to my wifi network, and connected to my computer. I tried scanning-- it worked fine. I tried copying-- it does that no problem. It took longer to install the drivers on my PC than set up the printer itself.

So are printers really as straight-forward as I experienced with this cheap used one, or am I just lucky?
