Ask HN: Are magic links suitable for all age groups?

When picking which authentication method(s) to offer as part of your service (a SaaS for example), did you take age groups (or other factors of digital comprehension) into account?

Has it shaped your choice of whether or not to offer magic links (one time passwords) as opposed to password authentication?

Would you offer magic links as part of a service that is mainly targeted at ages 50 and over?
