Every faculty and staff member as well as every student are eligible for network and email accounts. These accounts are setup by the network administrator after filling up a simple form by a new LAN user directly at the computer office on the 4th floor, room 409. ** CERGE-EI email accounts are "lifetime" accounts for all alumni, provided they are looked after by users. The size of mailboxes can be extended upon request in justified instances by contacting the Computer Office at [[helpdesk@cerge-ei.cz|]].**. | Every faculty and staff member as well as every student are eligible for network and email accounts.

It's difficult to remember a whole bunch of complex passwords, therefore it's recommended to use a password manager, for instance [[http://www.lastpass.com|www.lastpass.com]] for online usage or software based for offline usage [[http://keepass.info/|http://keepass.info/]]: you have to remember only one strong "master" password - the others are stored safely in a "vault". | It's difficult to remember a whole bunch of complex passwords, therefore it's recommended to use a password manager, for instance [[http://www.lastpass.com|www.lastpass.com]] for online usage or software based for offline usage [[http://keepass.info/|http://keepass.info/]]: you have to remember only one strong "master" password - the others are stored safely in a "vault". |

You can even use the same strong password for multiple logins, just add a "service identificator" - example for gmail would be "sTRONgPassW0rd@gmail", example for facebook could be "sTRONgPassW0rd@FB" - but security is lower than in separate complex passwords.. | You can even use the **same strong password** for __multiple logins__, just add a __"service identificator_ckgedit_QUOT___ - example for gmail would be "sTRONgPassW0rd@gmail", example for facebook could be "sTRONgPassW0rd@FB" - but security is lower than in separate complex passwords.. |
