A lecturer has just asked me if it's possible to

1. Import tokens (yes, I said as a CSV, there are field mappings)
2. Have participants go directly to the survey and enter their name or other detail and be validated and be able to take the survey.

I explained that I can generate tokens and send the email invite, but he thinks the students miss the emails. (This does sometimes happen, even though I got Microsoft to fix the incorrectly-identified-as-spam issue with the emails from our server)

Is this possible? Thanks very much.

Instead of passing the token at the link given to the students by email you can simply give them the link to the survey and let them enter a token (which you entered by csv upload) that uses a certain format like <birthdate><house number><last name>:
