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:

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

MessageError: Error: credential propagation was unsuccessful

I use this code:

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?

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?

I have some troubles configuring SNMP4J as SNMPv3 manager for a simple Get-Request. SNMPv2 is working properly, both using net-snmp and SNMP4J.

On my local machine I have a running snmp daemon (via net-snmp).

After updating the package Microsoft.AspNetCore.Authentication.JwtBearer from version 3.1.14 to 6.0.1, requests with authentication fail with 401 Unauthorized "invalid token".

What needs to be changed with the new package version?

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.

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.

Others mentioned that you simply log in with the Cloud SDK and ADC (Application Default Credentials) by doing:

Is possible to have the buttons "External Registration" placed inside .razor page (server side)?

The below code is from ExternalRegister.cshtml but I would like to have that two registration buttons (Google, Facebook) as part of the Start.razor page. Is that possible?
