PassGen allows you to generate long, hard to crack passwords for accounts that are managed by password management tools like PassMan. The passwords generated by this tool are not suitable for manual use because they would be very difficult to remember. If you are looking for a tool that creates passwords that are easier to remember try PassGenW.
PassMan provides you with a lot of flexibility for defining the characteristics of the generated passwords. You can specify the number of passwords generated, the minimum length, the maximum length, a custom prefix, a custom suffix, a filter and a custom alphabet (or character set).
To generate a list of password simply click the Generate button. You can clear the password list by clicking the Clear button.
The table below describes each of the fields.
| Field | Default | Description |
|---|---|---|
| Number of Passwords | 10 | The number of passwords to generate. |
| Minimum Length | 20 | The minimum password length. You never want this value to be less than 10. If the minimum length is changed to a value larger than the maximum length, the maximum length is automatically adjusted. |
| Maximum Length | 20 | The maximum password length. If the maximum length is changed to a value larger than the minimum length, the minimum length is automatically adjusted. |
| Custom Prefix |
The custom prefix that you want for each password.
One possible use of a custom prefix is to help organize
your passwords. For example all of your bank passwords may
have "bank/" as the prefix.
|
|
| Custom Suffix |
The custom suffix that you want for each password.
One possible use of a custom suffix is to help organize
your passwords. For example all of your bank passwords may
have "/bank" as the suffix.
|
|
| Filtering Pattern | ^.*$ |
The filter applied to password candidates to only keep the ones that match a certain
pattern as defined by the regular expression pattern.
The default is to accept all passwords.
For example, you could use it to guarantee that all of your passwords have "abc" as the first three characters by specifying something
like "^abc.*$".
When using filtering you must be careful to make sure that the patterns you are searching for are in the valid alphabet. For example if your specify "^abc.*$" but only
allow digits in your alphabet, no passwords will ever match and the
app will time out.
You also want to make sure that for patterns like "^abc"
you weight the lower case letters so that that have a much higher
probability of appearing. If you don't do that, it is more likely
to time out.
|
| Filtering Attributes | case insensitive | There is only one filtering attribute defined. When check it tells PassMan to do a case insensitive search. |
| Timeout (ms) | 500 | The maximum amount of time allowed to generate patterns. When the time is exceeded a timeout message pops up. The default is half a second. |
| Lowercase Letters | 1 |
The number of times to include lower case letters in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
For passwords where you want a lot of lower case letters to appear relative to other characters you would want to specify a value like 10. |
| Uppercase Letters | 1 |
The number of times to include upper case letters in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
For passwords where you want a lot of upper case letters to appear relative to other characters you would want to specify a value like 10. |
| Digits | 1 |
The number of times to include digits in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
For passwords where you want a lot of digits to appear relative to other characters you would want to specify a value like 10. |
| Hex Digits | 0 |
The number of times to include hex digits in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
For passwords where you want a lot of hex digits to appear relative to other characters you would want to specify a value like 10. |
| Selected Punctuation | 1 |
The number of times to include a subset of punctuation characters in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
For passwords where you want a lot of these characters to appear relative to other characters you would want to specify a value like 10. This is the subset of punctuation characters that I felt would the useful for passwords. You can define your own set in the custom section and the set the number to zero if you don't like my selection. |
| Punctuation | 0 |
The number of times to include punctuation characters in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
For passwords where you want a lot of punctuation characters to appear relative to other characters you would want to specify a value like 10. |
| Custom | 0 |
The number of times to include custom characters in
the final alphabet (character set) that is used to
generate the passwords. The more times that it is
included, the higher the probability that characters
from that set will appear in the final result.
You can even duplicate characters to increase the probability
that they will be used.
For passwords where you want a lot of custom characters to appear relative to other characters you would want to specify a value like 10. |
| Repeated Characters |
Allow |
If checked, then allow repeated characters like "aa" in the generated
passwords. Allowing repeated characters increases randomness but may
decrease entropy. Consider the case of a 10 character password that
is "aaaaaaaaaa". Although it is random, it is probably not very safe
from cracking.
The number of repeated characters describes the size of the sequence. |
These examples illustrate how to use the app.
You will see 10 passwords generated. ere is an example of the output. The first column is the count, the second column is the length of the password and the third column is the password.
The alphabet has 71 characters.
