Henle Library App requires your HfMDK e-mail address

On June 12, 2025, the HfMDK swit­ched the of­fi­ci­al com­mu­ni­ca­ti­on chan­nel to the uni­ver­si­ty­'s own e-mail ad­dres­ses. This also has con­se­quen­ces for the use of the Hen­le Li­bra­ry App:

In the fu­ture, Hen­le will only ac­cept your HfMDK email ad­dress when re­gis­te­ring and re­va­li­da­ting your ac­count. For this rea­son, Hen­le will con­tact you at the e-mail ad­dress you pre­vious­ly used and ask for your new HfMDK e-mail ad­dress. Plea­se re­spond prompt­ly and in­form Hen­le of your new ad­dress so that you can re­va­li­da­te your ac­count wi­t­hin the uni­ver­si­ty at any time.

It is best to do this be­fo­re the se­mes­ter break. If you then re­va­li­da­te your ac­count im­me­dia­te­ly, you will be able to use the da­ta­ba­se wi­t­hout restric­tions throughout the va­ca­ti­ons.
