Password security

 Your password is your most important protection against misuse of your data and identity – make sure that you create a strong password and do never disclose it to others.

At SDU, a password must meet the following complexity requirements:
1. password have at least 12 (twelve) characters
2. password includes capital letters and lower-case letters
3. password includes numbers
4. password includes special characters (like # ¤ % &)

However, it may be difficult to memorise a long string of characters and numbers. Therefore, you can work out a mnemonic rule while creating you password. Since the the following example is displayed on this website page, you should of course not use this in practice:

You can memorise this by means of the phrase:
You are born to be late
