Allow for weird single-use 2FA codes

[kmyhre]

Using Norwegian National authentication solution "MinID", single-use codes are only sometimes recognised in the autofill mode. They seem to always be five characters and containing both numbers and lower-case letters, and I'm guessing they are only recognised when containing two or more numbers.

On closer inspection, how many numbers are in the code does not appear to affect whether it is registered as a single-use code or not, as the underlined ones in the example above are correctly recognised, while the others are not..
