Self Service Password Reset
Met Self Service Password Reset (SSPR) is het mogelijk voor gebruikers om zelf hun wachtwoord
opnieuw instellen voor diverse ldap-diensten zonder tussenkomst van ict, zoals bijvoorbeeld de
netwerkschijven (H en I), intranet, vpn, Confluence, Jira en Surfmarkt.
Door middel van uitdagingsvragen kan een gebruiker bevestigen wie hij/zij is voordat ze hun
wachtwoorden veilig kunnen resetten.

SURFfilesender
SURFfilesender is een webgebaseerde applicatie waarmee geauthenticeerde gebruikers veilig en
gemakkelijk willekeurig grote bestanden naar andere gebruikers kunnen verzenden. Gebruikers zonder
een account kunnen een gastvoucher worden gestuurd door een geverifieerde gebruiker. SURFfilesender
is ontwikkeld volgens de eisen en wensen van onderwijs en onderzoek.

edu.nl: privacy-vriendelijke URL-shortener
edu.nl is dé URL-shortener voor onderwijs en onderzoek. Veilig omdat gebruikers inloggen met
SURFconext. Privacy-vriendelijk omdat edu.nl geen persoonlijke gegevens van gebruikers opslaat en
bezoekers van links niet trackt. edu.nl is kosteloos voor alle bij SURF aangesloten instellingen.
