Web Authentication solves many problems in secure online authentication, but also introduces some new challenges. One of the greatest challenges is loss of an authenticator - what can the user do to prevent being locked out of their account if they lose an authenticator?. The current workaround to this problem is to have the user register more than one authenticator, for example a roaming USB authenticator and a platform authenticator integrated into a smartphone. That way the user can still use the other authenticator to log in if they lose one of the two. However, this approach has drawbacks. What we would like to enable is for the user to have a separate backup authenticator which they could leave in a safe place and not keep with them day-to-day. This is not really feasible with the aforementioned workaround, since the user would have to register the backup authenticator with each new RP where they register their daily-use authenticator. This effectively means that the user must keep the backup authenticator with them, or in an easily accessible location, to not risk forgetting to register the backup authenticator, which largely defeats the purpose of the backup authenticator. Under the restriction that we don't want to share any secrets or private keys between authenticators, one simple way to solve this would be to import a public key from the backup authenticator to the primary authenticator, so that the primary authenticator can also register that public key with each RP. Then the backup authenticator can later prove possession of the private key and recover access to the account. This has a big drawback, however: a static public key would be easily correlatable between RPs or accounts, undermining much of the privacy protections in WebAuthn. In this document we propose a key agreement scheme which allows a pair of authenticators to agree on an EC key pair in such a way that the primary authenticator can generate nondeterministic public keys, but only the backup authenticator can derive the corresponding private keys. We present the scheme in the context of a practical application as a WebAuthn extension for account recovery. This enables the use case of storing the backup authenticator in a secure location, while maintaining WebAuthn's privacy protection of non-correlatable public keys.

QUESTION
Secret of Time-based One Time Password are usually 16-byte base32 encoded string. e.g. GitHub 2FA.
But for some scenario, it has 26 bytes long. e.g. Tutanota OTP. Often in lower case with whitespaces, like: vev2 qjea un45 3sr4 q4h3 ais4 ci
I tried with the TOTP algorithm implemented in dgryski/dgoogauth and tilaklodha/google-authenticator. Both can handle 16-byte secret well, but got error for 26-byte secret.
e.g. for 16-byte secret VEV2QJEAUN453SR4

ANSWER
Answered 2022-Apr-02 at 04:15A base32 encodes every 5 bits of input bytes into base32 character, go base32 use The RFC 4648 Base 32 alphabet (A-Z, 2-7). When decode a string to bytes, each base32 character input will be mapped to a 5 bit index then recompose to bytes.
In your example "VEV2QJEAUN453SR4Q4H3AIS4CI", the previous "VEV2QJEAUN453SR4" was already valid input, it is a 16 char input, and 5 bit * 16 is 80 bit so it can be resolved into 10 bytes output. Now let us just look at the rest "Q4H3AIS4CI", 10 char -> 5 * 10 = 50 bits, the previous 40 bits can be decode to 5 bytes, but the last 2 char "CI" leads 2 bit remainder
QUESTION
Since yesterday I have had the problem that I can no longer mount my Google account. Normally, when I run it, I get a link to authorize myself with. Now, when the code is executed, an extra browser window is opened where I should authorize myself. But if I do it over it, it doesn't work. Do you know why it can be that this authorization link is suddenly no longer shown? Any security setting maybe? I've tried several browsers.
EDIT: With the new authorization popup it works if i mount the google drive from the same google account like colab. But the problem is that my main google drive is on another account than Google Colab. With the link it used to work without any problems earlier...
EDIT 2: I have now solved it in such a way that I have shared the required folder for my other account and can now access it via my Colab Google Drive account. But I still didn't manage to get the link back.
After the code execution and authorization with the new popup i get this error message on Google Colab:
MessageError Traceback (most recent call last) in () 1 #Connect Google Drive 2 from google.colab import drive ----> 3 drive.mount('/gdrive')
3 frames /usr/local/lib/python3.7/dist-packages/google/colab/_message.py in read_reply_from_input(message_id, timeout_sec) 104 reply.get('colab_msg_id') == message_id): 105 if 'error' in reply: --> 106 raise MessageError(reply['error']) 107 return reply.get('data', None) 108

Answered 2021-Nov-07 at 20:45This is a problem with Google Colab Pro. I have a Pro account as well as a normal account. My normal account works as intended (with the link) whereas my Pro account has the pop-up window that gives me the same error as OP.
QUESTION
Good day all, I am building an app in flutter and I use firebase as the backend. I allow users register and sign into the app using their phone number (and then a password). However, I want to add an extra layer of uniqueness to the registration/login flow.
What I mean is that, I only want one a maximum of one account to be reachable from one device. If person A creates an account on phone A, they can only ever use the app from phone A. Person A should not be able to log into their account from phone B.
I do not believe an sms two factor is enough for this because person A can share the two factor code with person B. Person B would then be able to login to Person A's account on phone B because they have person A's phone number and 2 factor code.
Is there a way of implementing this for a flutter app running on firebase?
...ANSWER
Answered 2022-Mar-30 at 11:51You can try saving the unique device ID of the user upon registration then you can check on login whether the user is on that specific device. For getting the unique device ID, you can check here.
QUESTION
I was setting up my new Mac for my eks environment. After the installation of kubectl, aws-iam-authenticator and the kubeconfig file placement in default location. I ran the command kubectl command and got this error mentioned below in command block.
My cluster uses v1alpha1 client auth api version so basically i wanted to use the same one in my Mac as well.
I tried with latest version (1.23.0) of kubectl as well, still the same error. Whereas When i tried to do with aws-iam-authenticator (version 0.5.5) I was not able to download lower version.
Can someone help me to resolve it?
...ANSWER
Answered 2022-Mar-28 at 09:41I have the same problem
You're using aws-iam-authenticator
0.5.5
, AWS changed the way it behaves in 0.5.4
to require v1beta1
.
It depends on your configuration, but you can try to change the K8s context you're using to v1beta1
Otherwise switch back to aws-iam-authenticator
0.5.3
- you might need to build it from source if you're using the M1 architecture as there's no darwin-arm64
binary built for it

QUESTION
In the app, going File > Workspace > Sign in to new workspace launches a browser window. After selecting the workspace in browser, it launches back a deep link back to slack but it doesn't work. Nothing happens on the slack-desktop.
Attempting to find out what is going on, I run the /usr/bin/slack to take a look at the logs.
I see logs of HANDLE_DEEP_LINK but no follow up activity.
...ANSWER
Answered 2022-Jan-26 at 16:40After trying various things, I noticed that what I suspect to be the workspace id, tlvs8sasf
above are often in CAPS in the logs.
So, I tried updating the deep link by upper casing the workspace id, then click on it. Voila, it worked for me. Hope this helps anyone else also suffering from this same issue.

I searched a lot how to authenticate/authorize Google's client libraries and it seems no one agrees how to do it.
Some people states that I should create a service account, create a key out from it and give that key to each developer that wants to act as this service account. I hate this solution because it leaks the identity of the service account to multiple person.

PA and BA agree on a choice of two key derivation functions KDF1 and KDF2, and one message authentication code (MAC) function MAC. KDF1 outputs integers and KDF2 outputs values suitable as key inputs for MAC.
BA generates a new P-256 EC key pair with private key s and public key S.
BA sends S to PA.
RP chooses a unique public identifier rp_id. This is effectively a protocol constant and implicitly available to all parties at all times.
