KYC would really be the main problem here if you do engage with them lots of requirements and verification but you can still make use of it without verification but on limited amounts of transactions.

as stated, just get a phone for this. you can even use a virtual phone number but beware; if you lose access to that specific number you will be locked out of your account in certain circumstances.

Eventually I tried to perform the Authy initialization with my land-line anyway and it worked fine.  I imagine that people are trying to use various voice-routing or whatever and the system is getting balled up so Authy just dumped land-line use all together (fucking their down-stream customers such as Coinbase in the process without telling them since they seemed unaware and/or argumentative about Authy's policy shifts.)

Hi there,

I’m afraid without the ability to receive text messages you will be unable to verify your phone number with Coinbase.

Landlines are simply not supported.

Sorry to disappoint.

Hi there,

Thanks for reaching out. Having investigated the issue, I am working with a specialist to address it properly. We will follow-up with you as soon as we have an update.

Thank you for your patience.

i can verify my landline phone with these third party services? the
trouble im having is the authy extension for google chrome is saying
the codes im entering are invalid:

the 2FA token appears in the authy extension when i add my phone
number to the "verify my phone" dialog in the security tab on
coinbases website. when i do this the coinbase dialog says the codes
the token is providing are invalid. my system clock is confirmed
synchronized to the UTC and i am entering the codes correctly before
they expire.

Hi there,

If you do not have a smartphone, there are other apps that can be used on a computer that use the same protocol and provide similar security to Google Authenticator.

Some example applications* that use the same protocol and display the same types of codes include:

    https://1password.com/
    https://winauth.com/download/

These applications can be activated and used with Coinbase instead of Google Authenticator by following the same procedures. Just use the code generated in the app you choose anywhere you are asked for an authenticator app code!

I hope that helps!

Thank you for contacting Coinbase Support!

i still do not understand. can you please send me a super simple clear
answer? i do not have a cell phone and am not going to buy one. i do
have a landline phone and a computer. is it possible for me to
buy/sell bitcoins on coinbase.com without a cell phone? thanks

Hi there,

Thank you for contacting us about this, and my apologies for the trouble.

For security reasons, we’re no longer able to support 2-factor verification codes via voice call. If you’re using a landline, or your phone does not have SMS capabilities, please perform a phone number change to use a number capable of receiving SMS messages instead. To do this, please follow these instructions:

    Login normally to your Coinbase account with your username and password.
    Once you have logged in successfully with your login credentials, click on the link “Code not working?”
    Click on “I no longer own the phone number ending in +1 xxx xxx 1234” (as an example)
    You will be prompted to start an Account Recovery process for your security codes.

Please note that this process may take 48-72 hours to complete. This process will only work if you are using SMS for your security codes – not an app.

You will receive a confirmation that the process has been completed. Then you will start receiving your codes on your new phone. If you do not receive your codes on your new phone, or have any issues, please let us know.

Thank you for using Coinbase.

Is it possible to verify my landline phone to use on coinbase.com? I cant find a clear answer online. i have tried to use google chrome and the authy app for google chrome but it keeps telling the code is invalid.

bottom line: is coinbase.com restricted to cell phone users only?
