how could I proceed?

Hi,

It's weird, your export file is missing a property normally available in 2FAs export. Could you open the 2fas file with a text editor and check how are composed the otp objects?
They look like this, except that at least one of them does not contain the algorithm property:

"otp":
{
    "account": "My account",
    "digits": 6,
    "counter": 0,
    "period": 30,
    "algorithm": "SHA1",
    "tokenType": "TOTP"
}

How many don't have the algorithm property? For them, what is their tokenType?

[captainabloc]

Hi,
I have 6 objects. Upon those 6, one only hasn't the algorithm property.
this is the one for ssh totp:

otp{6}
link:otpauth://totp/account?secret=supersecret&issuer=access
label:ssh@access
account:myaccounts
issuer:access
tokenType:TOTP
source:Link

and indeed, this is the only one not having

    "digits": 6,
    "counter": 0,
    "period": 30,
    "algorithm": "SHA1",

infos

and nice catch!
removing that one from the file makes it working!

thanks for the trick.

Do you, by chance, know a solution to get that one working too?

This is what I'm currently looking for. For now all the exports I made with 2FAs always had these missing props.

Can you try this:

• Edit your export and add the following properties to the ssh item:

    "digits": 6,
    "period": 30,
    "algorithm": "SHA1",
  

• Import to 2FAuth, you shouldn't face any error
• Generate a code for the ssh account in 2FAuth then compare it to a code generated by 2FAs.

Do you get the same code?
Is there anything special about how this ssh account was registered into 2FAs?

[captainabloc]

you rock!
working perfect now, thanks and congrats for your project.
