## page was renamed from FAQ/Why can't I use my JMP number for two-factor authentication (2FA)??

Context: https://blog.jmp.chat/b/2022-sms-account-verification

Some companies maintain secret lists of phone numbers which they prohibit for new signups.
If you run into this problem, you can:
* try again (sometimes this solves the issue)
* contact the company, letting them know of the issue
* use a different form of 2FA, like OTP (since SMS 2FA is neither [[https://www.cnet.com/news/facebooks-two-factor-authentication-with-phone-numbers-puts-security-and-privacy-at-odds/|private]], nor is it all that [[https://www.howtogeek.com/310418/why-you-shouldnt-use-sms-for-two-factor-authentication/|secure]]
* find an alternative to that company's services
* use a service specifically tailored to SMS verification instead, like https://crypton.sh/ or https://juicysms.com/ // (their numbers might not be on these block lists, but they lack certain other features of a JMP phone number)
* Ask JMP support about the Premium+ route

Tangerine Bank, , 2, 2024-12, , 2, 2024-09, SMS does not work reliably. Choosing home phone to receive the security code via a phone call does fix the problem. If you prefer to use SMS: The number they send the SMS from is (864732;phone-context=ca-us.phone-context.soprani.ca@cheogram.com). I added the number in my contact and when trying to authenticate I found that if I text "help" or "status" to that number and then I re-click "re-send sms" it does actually seem to come reliably after a few seconds. It's finicky but it's worked every time.

Wells Fargo, , , , , 1, 2024-Feb, I was able to add a JMP number to my account. When I authenticate the number isn't listed as a 2FA option. This degrades the features of the website (such as OAuth with an aggregator).
WhatsApp, 1, 1, 2023-07, 4, 2, 2024-10-27, Tried registering with WhatsApp with a US-based number today. Failed with message: "<your number> is not a valid mobile number for the country United States". Another jmp user reported the same thing yesterday. Canadian numbers also get the same message

Zelle, , , , 3, , 2024-07-16, On signup using the Zelle mobile app the app reports the error "For security reasons you have been logged out." Called customer support and was told that VOIP numbers are not supported. Banks/credit unions that support Zelle natively may not have a phone number requirement so you may still be able to use Zelle in this case without a phone number. Second: received a message of "We're sorry, but the number provided is not a valid US mobile number. Please provide a valid US mobile number." However, able to use a SimpleLogin alias as e-mail for Zelle.
